This patch removes the target macro LIBGCC2_LONG_DOUBLE_TYPE_SIZE.

After recent changes, this macro was used in two ways in libgcc: to
determine the mode of long double in dfp-bit.h, and to determine
whether a particular mode has excess precision for use in complex
multiplication.

The former is concerned specifically with long double: it relates to
use of strtold for converting between decimal and binary floating
point.  This is replaced by comparing __LDBL_MANT_DIG__ with the
appropriate __LIBGCC_*_MANT_DIG__ macro.  The latter is replaced
__LIBGCC_*_EXCESS_PRECISION__ predefined macros.

Remarks:

* Comparing (__LDBL_MANT_DIG__ == __LIBGCC_XF_MANT_DIG__) is more
  fragile than it looks; it's possible for XFmode to have 53-bit
  mantissa (TARGET_96_ROUND_53_LONG_DOUBLE, on FreeBSD and
  DragonFlyBSD 32-bit), in which case such a comparison would not
  distinguish XFmode and DFmode as possible modes for long double.
  Fortunately, no target supporting that form of XFmode also supports
  long double = double (but if some target did, we'd need e.g. an
  additional macro giving the exponent range of each mode).

  Furthermore, this code doesn't actually get used for x86 (or any
  other target with XFmode support), because x86 uses BID not DPD and
  BID has its own conversion code (which handles conversions for both
  XFmode and TFmode without needing to go via strtold).  And FreeBSD
  and DragonFlyBSD aren't among the targets with DFP support.  So
  while in principle this code is fragile and it's a deficiency that
  it can't support both XFmode and TFmode at once (something that
  can't be solved with the string conversion approach without libc
  having TS 18661 functions such as strtof128), all these issues
  should not be a problem in practice.

* If other cases of excess precision are supported in future, the code
  for defining __LIBGCC_*_EXCESS_PRECISION__ may need updating.
  Although the most likely such cases might not actually involve
  excess precision for any mode used in libgcc - FLT_EVAL_METHOD being
  32 to do _Float16 arithmetic on _Float32 should have the effect of
  _Complex _Float16 arithmetic using __mulsc3 and __divsc3, rather
  than currently nonexistent __mulhc3 and __divhc3 as in bug 63250 for
  ARM.

* As has been noted in the context of simultaneous support for
  __float128 and __ibm128 on Power, the semantics of macros such as
  LONG_DOUBLE_TYPE_SIZE are problematic because they rely on a
  poorly-defined precision value for floating-point modes (which seems
  to be intended as the number of significant bits in the
  representation, e.g. 80 for XFmode which may be either 12 or 16
  bytes) uniquely identifying a mode (although defining an arbitrarily
  different value for one of the modes you wish to distinguish may
  work as a hack).  It would be cleaner to have a target hook that
  gives a machine mode directly for float, double and long double,
  rather than going via these precision values.  By eliminating all
  use of these macros (FLOAT_TYPE_SIZE, DOUBLE_TYPE_SIZE,
  LONG_DOUBLE_TYPE_SIZE) from code built for the target, this patch
  facilitates such a conversion to a hook (which I suppose would take
  some suitable enum as an argument to identify which of the three
  types to return a mode for).

  (The issue of multiple type support for DFP conversions would apply
  in that Power case.
  <https://gcc.gnu.org/ml/gcc-patches/2014-07/msg01084.html> doesn't
  seem to touch on it, but it would seem reasonable to punt on it
  initially as hard to fix.  There would also be the issue of getting
  functions such as __powikf2, __mulkc3, __divkc3 defined, but that's
  rather easier to address.)

This patch removes the (undocumented) LIBGCC2_TF_CEXT target macro,
replacing it by -fbuilding-libgcc predefines (and thereby gets rid of
another LIBGCC2_LONG_DOUBLE_TYPE_SIZE conditional, though some more
patches are needed before that target macro can be eliminated).  This
macro indicated the suffix used on __builtin_huge_val,
__builtin_copysign, __builtin_fabs built-in function names to produce
the names for a given floating-point mode.

Predefines are added for all floating-point modes supported for
libgcc, not just TFmode.  These are fully accurate for modes
corresponding to float, double and long double.  For other modes, the
suffix for *constants* is determined by the targetm.c.mode_for_suffix
hook (the limit to two possible suffixes 'w' and 'q' being hardcoded
in various places).  This is in fact the suffix for built-in functions
as well where such functions exist.

* For i386, the *q functions always exist (whether or not TFmode is
  used for long double).  The *w functions never exist (but this
  doesn't matter for libgcc, since no i386 configuration treats XFmode
  as a supported scalar mode if long double is TFmode; if __float80
  were to be supported for 64-bit Android, properly such functions
  ought to be added).

* For ia64, the *q functions exist for non-HP-UX (under HP-UX, long
  double is TFmode, so they aren't needed).  The *w functions never
  exist.  This is an issue for this libgcc code for the XFmode complex
  functions in libgcc on HP-UX; as I understand it, right now those
  will accidentally be using TFmode versions of those three functions,
  so involving unnecessary conversions, while the sanity check on CEXT
  accidentally passes because all it tests is the sizes of the types.

Because of the lack of 'w' functions, the patch uses 'l' when the
constant suffix is 'w', matching what the existing libgcc code would
do for IA64 HP-UX in that case.

Ideally there would be generic code to create such built-in functions
for all supported floating-point types.  That may be something to
consider if support for TS 18661-3 (standard bindings for IEEE
754-2008, defining names such as _Float128, and function names such as
copysignf128) is added in future.

The i386 sfp-machine.h defines FP_TRAPPING_EXCEPTIONS in a way that is
always wrong: it treats a set bit as indicating the exception is
trapping, when actually a set bit (both for 387 and SSE floating

trapping.  This patch fixes this bug.

This patch removes the LIBGCC2_HAS_{SF,DF,XF,TF}_MODE target macros,
replacing them by predefines with -fbuilding-libgcc, together with a
target hook that can influence those predefines when needed.

The new default is that a floating-point mode is supported in libgcc
if (a) it passes the scalar_mode_supported_p hook (otherwise it's not
plausible for it to be supported in libgcc) and (b) it's one of those
four modes (since those are the modes for which libgcc hardcodes the
possibility of support).  The target hook can override the default
choice (in either direction) for modes that pass
scalar_mode_supported_p (although overriding in the direction of
returning true when the default would return false only makes sense if
all relevant functions are specially defined in libgcc for that
particular target).

The previous default settings depended on various settings such as
LIBGCC2_LONG_DOUBLE_TYPE_SIZE, as well as targets defining the above
target macros if the default wasn't correct.

The default scalar_mode_supported_p only declares a floating-point
mode to be supported if it matches one of float / double / long
double.  This means that in most cases where a mode is only supported
conditionally in libgcc (TFmode only supported if it's the mode of
long double, most commonly), the default gets things right.  Overrides
were needed in the following cases:

* SFmode would always have been supported in libgcc (the condition was
  BITS_PER_UNIT == 8, true for all current targets), but pdp11
  defaults to 64-bit float, and in that case SFmode would fail
  scalar_mode_supported_p.  I don't know if libgcc actually built for
  pdp11 (and the port may well no longer be being used), but this
  patch adds a scalar_mode_supported_p hook to it to ensure SFmode is
  treated as supported.

* Certain i386 and ia64 targets need the new hook to match the
  existing cases for when XFmode or TFmode support is present in
  libgcc.  For i386, the hook can always declare XFmode to be
  supported - the cases where it's not are the cases where long double
  is TFmode, in which case XFmode fails scalar_mode_supported_p[*] -
  but TFmode support needs to be conditional.  (And of the targets not
  defining LIBGCC2_HAS_TF_MODE before this patch, some defined
  LONG_DOUBLE_TYPE_SIZE to 64, so ensuring LIBGCC2_HAS_TF_MODE would
  always be false, while others did not define it, so allowing it to
  be true in the -mlong-double-128 case.  This patch matches that
  logic, although I suspect all the latter targets would have been
  broken if you tried to enable -mlong-double-128 by default, for lack
  of the soft-fp TFmode support in libgcc, which is separately
  configured.)

  [*] I don't know if it's deliberate not to support __float80 at all
  with -mlong-double-128.

In order to implement the default version of the new hook,
insn-modes.h was made to contain macros such as HAVE_TFmode for each
machine mode, so the default hook can contain conditionals on whether
XFmode and TFmode exist (to match the hardcoding of a list of modes in
libgcc).  This is also used in fortran/trans-types.c; previously it
had a conditional on defined(LIBGCC2_HAS_TF_MODE) (a bit dubious,
since it ignored the value of the macro), which is replaced by testing
defined(HAVE_TFmode), in conjunction with requiring
targetm.libgcc_floating_mode_supported_p.

(Fortran is testing something stronger than that hook: not only is
libgcc support required, but also libm or equivalent.  Thus, it has a
test for ENABLE_LIBQUADMATH_SUPPORT in the case that the mode is
TFmode and that's not the same as any of the three standard types.
The old and new tests are intended to accept exactly the same set of
modes for all targets.)

Apart from the four target macros eliminated by this patch, it gets us
closer to eliminating LIBGCC2_LONG_DOUBLE_TYPE_SIZE as well, though a
few more places using that macro need changing first.
