This patch uses IFN_COND_* to vectorise conditionally-executed,
potentially-trapping arithmetic, such as most floating-point
ops with -ftrapping-math.  E.g.:

    if (cond) { ... x = a + b; ... }

becomes:

    ...
    x = .COND_ADD (cond, a, b, else_value);
    ...

When this transformation is done on its own, the value of x for
!cond isn't important, so else_value is simply the target's
preferred_else_value (i.e. the value it can handle the most
efficiently).

However, the patch also looks for the equivalent of:

    y = cond ? x : c;

in which the "then" value is the result of the conditionally-executed
operation and the "else" value "c" is some value that is available at x.
In that case we can instead use:

    x = .COND_ADD (cond, a, b, c);

and replace uses of y with uses of x.

The patch also looks for:

    y = !cond ? c : x;

which can be transformed in the same way.  This involved adding a new
utility function inverse_conditions_p, which was already open-coded
in a more limited way in match.pd.

This patch adds support for fusing a conditional add or subtract
with a multiplication, so that we can use fused multiply-add and
multiply-subtract operations for fully-masked reductions.  E.g.
for SVE we vectorise:

  double res = 0.0;
  for (int i = 0; i < n; ++i)
    res += x[i] * y[i];

using a fully-masked loop in which the loop body has the form:

  res_1 = PHI<0(preheader), res_2(latch)>;
  avec = .MASK_LOAD (loop_mask, a)
  bvec = .MASK_LOAD (loop_mask, b)
  prod = avec * bvec;
  res_2 = .COND_ADD (loop_mask, res_1, prod, res_1);

where the last statement does the equivalent of:

  res_2 = loop_mask ? res_1 + prod : res_1;

(operating elementwise).  The point of the patch is to convert the last
two statements into:

  res_s = .COND_FMA (loop_mask, avec, bvec, res_1, res_1);

which is equivalent to:

  res_2 = loop_mask ? fma (avec, bvec, res_1) : res_1;

(again operating elementwise).

This patch adds match.pd support for applying normal folds to their
IFN_COND_* forms.  E.g. the rule:

  (plus @0 (negate @1)) -> (minus @0 @1)

also allows the fold:

  (IFN_COND_ADD @0 @1 (negate @2) @3) -> (IFN_COND_SUB @0 @1 @2 @3)

Actually doing this by direct matches in gimple-match.c would
probably lead to combinatorial explosion, so instead, the patch
makes gimple_match_op carry a condition under which the operation
happens ("cond"), and the value to use when the condition is false
("else_value").  Thus in the example above we'd do the following

(a) convert:

      cond:NULL_TREE (IFN_COND_ADD @0 @1 @4 @3) else_value:NULL_TREE

    to:

      cond:@0 (plus @1 @4) else_value:@3

(b) apply gimple_resimplify to (plus @1 @4)

(c) reintroduce cond and else_value when constructing the result.

Nested operations inherit the condition of the outer operation
(so that we don't introduce extra faults) but have a null else_value.
If we try to build such an operation, the target gets to choose what
else_value it can handle efficiently: obvious choices include one of
the operands or a zero constant.  (The alternative would be to have some
representation for an undefined value, but that seems a bit invasive,
and isn't likely to be useful here.)

I've made the condition a mandatory part of the gimple_match_op
constructor so that it doesn't accidentally get dropped.

As part of the transition from the original support for named FPUs to
general FPU properties I defined an entry in the CPU definitions in
arm-cpus.in to use a named FPU.  However, that has now outlived its
usefulness and increasingly we are likely to find that newer cores do
not fit the legacy FPU names very well.  Furthermore it is now possible
to encode all the FPU capatilities directly in the ISA definitions, often
as simply as using +fp or +simd.

So this patch removes the fpu field from the "define cpu" entries and
instead encodes the same information in the isa field.  This also alows us
to remove a bit of now-dead code from parsecpu.awk.

	* config/arm/arm-cpus.in: Move information from fpu field of each
	cpu definition to the isa field.
	* config/arm/parsecpu.awk (fpu): Delete match rule.
	(gen_comm_data): Don't add bits from the CPU's FPU entry.

    The spec says that when an index expression appears on the left hand
    side of an assignment, the operands should be evaluated. The
    gofrontend code was assuming that that only referred to the index
    operand. But discussion of https://golang.org/issue/23188 has
    clarified that this means both the slice/map/string operand and the
    index operand. Adjust the gofrontend code accordingly.
    
    Fixes golang/go#23188
