This patch simplifies the table of CPUs supported in GCC by making
use of the new alias feature.  Most of the changes are fairly
straight-forward:
- arm7tdmi and arm7tdmi-s are the same thing.
- arm710t, arm720t and arm740t differ only in features external to the core
- arm920 and arm920t are the same thing; arm922t and arm940t differ from
  arm920t only in features external to the core; ep9312 is an arm920t-derived
  core that we continue to recognize for legacy reasons.
- arm10tdmi and arm1020t differ only in features external to the core.
- arm9e, arm946te-s, arm966e-s and arm968e-s differ only in features external
  to the core.
- arm10e, arm1020e and arm1022e differ only in features external to the core.

The arm10e/arm1020e/arm1022e change is the only one which changes
behaviour of the compiler slightly.  Previously, and for no reason
that I can remember, the scheduler for arm1020e/arm1022e was not used
for arm10e: this was probably an oversight.  The unification means
that the same scheduler is now used for all three cores.

	(arm7tdmi-s): Delete CPU.

	(arm920, arm922t, arm940t): Delete CPUs.

	(arm10e): Add aliases for arm1020e and arm1022e.
	(arm1020e, arm1022e): Delete CPU.
	* config/arm/arm.md (generic_sched): Remove entries that are now
	handled by aliases.
	(generic_vfp): Likewise.
	* config/arm/arm1020e.md: Simplify tuning selection based on alias

From-SVN: r265958

When in_a resolves to a register set in the prev_clobber insn, we may
use the SET_SRC for the compare instead.  However, when in_b so
resolves, we proceed to use the reg with its earlier value.  When both
resolve to the same register and prev_clobber is an insn that modifies
the register, this arrangement may cause the compare to match (when it
shouldn't) and the elimination of the compare to incorrectly succeed.

(set (reg 1) (plus (reg 1) (const_int N)))
(set (reg 2) (reg 1))
(set (reg flags) (compare (reg 1) (reg 2)))

in_a: (reg 1)            --> (plus (reg 1) (const_int N))
in_b: (reg 2) -> (reg 1) -/> oops

(parallel [
 (set (reg flags) (compare (plus (reg 1) (const_int N))
                           (reg 1))) ;; should be (plus...)
 (set (reg 1) (plus (reg 1) (const_int N)))])
(set (reg 2) (reg 1))

This patch arranges for in_b to also undergo SET_SRC substitution
when appropriate, with a shortcut for when in_a and in_b are the same
rtx.

Before revision 254025, we'd reject UNSPECs in debug loc exprs.
TARGET_CONST_NOT_OK_FOR_DEBUG_P still rejects that by default, on all
ports that override it, except for x86, that accepts @gotoff unspecs.
We can indeed accept them in top-level expressions, but not as
subexpressions: the assembler rejects the difference between two
@gotoff symbols, for example.

We could simplify such a difference and drop the @gotoffs, provided
that the symbols are in the same section; we could also accept
@gotoffs plus literal constants.  However, accepting those but
rejecting such combinations as subexpressions would be ugly, and most
likely not worth the trouble: sym@gotoff+litconst hardly makes sense
as a standalone expression, and the difference between @gotoffs should
be avoided to begin with, as follows.

Ideally, the debug loc exprs would use the symbolic data in
REG_EQUIV/REG_EQUAL notes, or delegitimized addresses, instead of
simplifying the difference between two legitimized addresses so that
the occurrences of the GOT register cancel each other.  That would
require some more elaborate surgery in var-tracking and cselib than
would be appropriate at this stage.

This patch adds support for defining an alias for a CPU name that can
then be used in conjunction with the -mcpu option in the same way that
the primary name can be used.  Aliases do not lead to a short-cut of
the feature options; they are literally an alternative name for the
core CPU.

The new entry in arm-cpus.in allows a cpu definition to contain an
alias statement, for example

begin cpu strongarm
 alias strongarm110 !strongarm1100 !strongarm1110
 ...
end cpu strongarm

each entry in the list represents another alias for the CPU.  If the
alias name starts with an exclamation mark, then it will match as for
any other alias (sans the ! itself), but it will not be listed in any
of the CPU hinting options (the intent is to make the alias
essentially undocumented).  In the above example, hints would be
provided for strongarm and strongarm110, but not for strongarm1100 or
strongarm1110.

The advantage of using aliases in this way is that it allows us to
reduce the number of duplicate table entries and identifier tags used
inside the compiler itself.

	(/begin cpu/): Check that the cpu name hasn't been previously defined.
	(gen_comm_data): Print out CPU alias tables.

This patch ports various fprintf calls in the inlining code to using
the dump API, using the %C format code for printing cgraph_node *.
I focussed on the dump messages that seemed most significant to
end-users; I didn't port all of the calls.

Doing so makes this information appear in -fopt-info and in
optimization records, rather than just in the dump_file.

It also changes the affected dumpfile-dumps from being unconditional
(assuming the dump_file is enabled) to being guarded by the MSG_*
status.  Hence various tests with dg-final scan-*-dump directives
need to gain "-all" or "-optimized" suffixes to -fdump-ipa-inline.

The use of %C throughout also slightly changes the dump format for
several messages, e.g. changing:

 Inlining void inline_me(char*) into int main(int, char**).

to:

../../src/gcc/testsuite/g++.dg/tree-ssa/inline-1.C:13:8: optimized:  Inlining void inline_me(char*)/0 into int main(int, char**)/2.

amongst other things adding "/order" suffixes to the cgraph node
names.

Numerous formatted messages from the inliner use %f, mostly as %f, but
occasionally with length modifiers.

This patch implements the simplest case of "%f" for pp_format (with no
modifier support) to make it easier to port these messages from fprintf
to dump_printf_loc.

The selftest has an assertion that %f on 1.0 is printed as "1.000000".
This comes from the host's sprintf, and I believe this is guaranteed by
POSIX: "If the precision is missing, it shall be taken as 6".  If this is
an issue I can drop the selftest.

	* c-format.c (gcc_dump_printf_char_table): Add entry for %f.

	* pretty-print.c (pp_format): Handle %f.

This patch implements support for %C in dump_printf for dumping
cgraph_node *.
(I would have preferred to have a code for printing symtab_node *

this approach).

	(gcc_dump_printf_char_table): Add entry for %C.
	(get_pointer_to_named_type): New function, taken from the handling

This patch adds a selftest fixture for overriding the "symtab" global,
so that selftests involving symtab nodes can be isolated from each
other: each selftest can have its own symbol_table instance.

In particular, this ensures that nodes can have a predictable "order"
and thus predictable dump names within selftests.

gcc/ChangeLog:
	* cgraph.c: Include "selftest.h".
	(saved_symtab): New variable.
	(selftest::symbol_table_test::symbol_table_test): New ctor.
	(selftest::symbol_table_test::~symbol_table_test): New dtor.
	(selftest::test_symbol_table_test): New test.
	(selftest::cgraph_c_tests): New.
	* cgraph.h (saved_symtab): New decl.
	(selftest::symbol_table_test): New class.
	* selftest-run-tests.c (selftest::run_tests): Call
	selftest::cgraph_c_tests.
	* selftest.h (selftest::cgraph_c_tests): New decl.
