A previous change to simplify LRA introduced in 11b809 (From-SVN: r279550)
disabled hard register splitting for -O0. This causes a problem on aarch64 in
cases where parameters are passed in multiple registers (in the bug report an OI
passed in 2 V4SI registers). This is mandated by the AAPCS.

The __3way_builtin_ptr_cmp concept can use three_way_comparable_with to
check whether <=> is valid. Doing that makes it obvious that the
disjunction on compare_three_way::operator() is redundant, because
the second constraint subsumes the first.

The workaround for PR c++/91073 can also be removed as that bug is fixed
now.

Comments 11-16 within PR analyzer/93316 discuss an ICE in some setjmp
tests seen on AIX and powerpc-darwin9.

The issue turned out to be an implicit assumption that longjmp is
marked "noreturn".  There are two places in engine.cc where the code
attempted to locate the longjmp GIMPLE_CALL by finding the final stmt
within its supernode, in one place casting it via "as_a <gcall *>",
in the other using it as the location_t of the
"rewinding from longjmp..." event.

When longjmp isn't marked noreturn, its basic block and hence supernode
can have additional stmts after the longjmp; in the setjmp-3.c case
this was a GIMPLE_RETURN, leading to a ICE when casting this to a
GIMPLE_CALL.

This patch fixes the two places in question to use the
  rewind_info_t::get_longjmp_call
member function introduced by 342e14ff,
fixing the ICE (and ensuring the correct location_t is used for events).

	PR analyzer/93316

This patch started as work to resole Richard's comment on quadratic lookups
in resolve_speculation. While doing it I however noticed multiple problems
in the new speuclative call code which made the patch quite big. In
particular:
 1) Before applying speculation we consider only targets with at lest
    probability 1/2.
    If profile is sane at most two targets can have probability greater or
    equal to 1/2. So the new multi-target speculation code got enabled only
    in very special scenario when there ae precisely two target with precise
    probability 1/2 (which is tested by the single testcase).

    As a conseuqence the multiple target logic got minimal test coverage and
    this made us to miss several ICEs.
 2) Profile updating in profile merging, tree-inline and indirect call
    expansion was wrong which led to inconsistent profiles (as already seen
    on the testcase).
 3) Code responsible to turn speculative call to direct call was broken for
    anything with more than one target.
 4) There were multiple cases where call_site_hash went out of sync which
    eventually leads to an ICE..
 5) Some code expects that all speculative call targets forms a sequence in
    the callee linked list but there is no code to maintain that invariant
    nor a verifier.
Fixing this it became obvious that the current API of speculative_call_info is
not useful because it really builds on fact tht there are precisely three
components (direct call, ref and indirect call) in every speculative call
sequence.  I ended up replacing it with iterator API for direct call
(first_speculative_call_target, next_speculative_call_target) and accessors for
the other coponents updating comment in cgraph.h.

Finally I made the work with call site hash more effetive by updating edge
manipulation to keep them in sequence. So first one can be looked up from the
hash and then they can be iterated by callee.

There are other things that can be improved (for example the speculation should
start with most common target first), but I will try to keep that for next
stage1. This patch is mostly about getting rid of ICE and profile corruption
which is a regression from GCC 9.

When I implemented the [over.match.ref] rule that a reference conversion
function needs to match l/rvalue of the target reference type it changed our
handling of this testcase.  It seems to me that our current behavior is what

Changed in v2:
- rename from warning_with_metadata_at to warning_meta
- fix test plugins

While C++ can have overloads, xgettext can't deal with overloads that have
different argument positions, leading to two failures in "make gcc.pot":

emit_diagnostic_valist used incompatibly as both
--keyword=emit_diagnostic_valist:4
--flag=emit_diagnostic_valist:4:gcc-internal-format and
--keyword=emit_diagnostic_valist:5
--flag=emit_diagnostic_valist:5:gcc-internal-format

warning_at used incompatibly as both
--keyword=warning_at:3 --flag=warning_at:3:gcc-internal-format and
--keyword=warning_at:4 --flag=warning_at:4:gcc-internal-format

The emit_diagnostic_valist overload isn't used anywhere (I think it's
a leftover from an earlier iteration of the analyzer patch kit).

The warning_at overload is used throughout the analyzer but nowhere else.

Ideally I'd like to consolidate this argument with something
constructable in various ways:
- from a metadata and an int or
- from an int (or, better an "enum opt_code"),
so that the overload happens when implicitly choosing the ctor, but
that feels like stage 1 material.

In the meantime, fix xgettext by deleting the unused overload and
renaming the used one.

The clever hack of '#define __has_include __has_include' breaks -dD
and -fdirectives-only, because that emits definitions.  This turns
__has_include into a proper builtin macro.  Thus it's never emitted
via -dD, and because use outside of directive processing is undefined,
we can just expand it anywhere.

It's wrong to assume that clock_gettime is unavailable on any *-*-linux*
target that doesn't have glibc 2.17 or later. Use a generic test instead
of using __GLIBC_PREREQ. Only do that test when is_hosted=yes so that we
don't get an error for cross targets without a working linker.

This ensures that C library's clock_gettime will be used on non-glibc
targets, instead of an incorrect syscall to SYS_clock_gettime.

	PR libstdc++/93325
	* acinclude.m4 (GLIBCXX_ENABLE_LIBSTDCXX_TIME): Use AC_SEARCH_LIBS for
	clock_gettime instead of explicit glibc version check.
	* configure: Regenerate.
