[AArch64][1/2] Implement TARGET_ESTIMATED_POLY_VALUE
The hook TARGET_ESTIMATED_POLY_VALUE allows a target to give an estimate for a poly_int run-time value.
It is used exclusively in tuning decisions, things like estimated loop iterations, probabilities etc.
It is not relied on for correctness.
If we know the SVE width implemented in hardware we can make more more
informed decisions in the implementation of TARGET_ESTIMATED_POLY_VALUE,
even when compiling for VLA vectorisation.
This patch adds an sve_width field to our tuning structs and sets it for
the current CPU tunings.
A new value is introduced to the aarch64_sve_vector_bits_enum enum that indicates
that SVE is not available: SVE_NOT_IMPLEMENTED. I set it to the same value as SVE_SCALABLE
so that parts of the aarch64 backend that follow the pattern:
if (vector_width == SVE_SCALABLE)
do_vla_friendly_action ()
else
assume_specific_width_for_correctness ()
continue to work without change, but the CPU tuning structs can use a more
appropriate moniker for indicating the absence of SVE.
This sets sve_width to SVE_NOT_IMPLEMENTED for all cores.
I aim to add an -moverride switch in the next patch that allows a power user to experiment
with different values of it for investigations.

[PR86747] tsubst friend tpl ctxt before looking it up for dupes
When a member template is redeclared as a friend, we enter the context
of the member before looking it up, and then we check that the decls
are compatible. However, when the member template references template
types of the enclosing context, say an enclosing template class, the
compare fails because the friend decl is already tsubsted, whereas the
looked up name isn't.
The problem is that the enclosing context is taken from the friend
declaration before tsubsting it, so we look up in the context of the
generic template instead of that of the tsubsted one we're
specializing. The solution is to tsubst the enclosing context when
it's a non-namespace scope.

[PR86397] resolve nondependent noexcept specs early in C++1[14]
build_noexcept_spec refrained from resolving nondependent noexcept
expressions when they were not part of the function types (C++ 11 and
14). This caused problems during mangling: canonical_eh_spec, when
called on the template function type, would find an unresolved but not
explicitly deferred expression, and nothrow_spec_p would reject it.
We could relax the mangling logic to skip canonical_eh_spec, but since
-Wnoexcept-type warns when mangling function names that change as
noexcept specs become part of types and of mangling in C++17, and the
test at mangling time may give incorrect results if the spec is not
resolved, we might as well keep things simple and resolve nondependent
noexcept specs sooner rather than later. This is what this patch does.

avoid null ptr deref in cselib_record_sets
Jeff Law tells me h8300-elf fails gcc.c-torture/compile/pr49029.c

The problem is that strict low part handling in cselib_record_sets
assumes src_elt is not NULL. That src_elt is taken from a strict low
part set, but it won't always have a src_elt to begin with. In this
case, it's because src is a volatile MEM; we don't record values for
those.
Although we could fix the problem by testing for a NULL src_elt before
creating the zero extends corresponding to strict low part sets of
formerly const0_rtx REGs, there's no point in recording the additional
set that we won't be able to use anyway.
We could still record that the whole register has a zero-extend of
the value stored in the narrower-mode strict low part of the register,
but is that of any use? I guess not, but if we find otherwise, we can
change that later.

[rs6000] Fix x86-compat vector intrinsics testcases for BE, 32bit
Fix general endian issues found in the test cases for thecompatibility
implementations of the x86 vector intrinsics. (The tests had been
inadvertently made to PASS without actually running the test code.
A later patch fixes this issue.)
Additionally, a new <smmintrin.h> is added, as some of the APIs therein are
now used by the test cases. It is _not_ a complete implementation of the
SSE4 interfaces, only the few "extract" interfaces uses by the tests.

Darwin fix libstdc++ build warnings.
GCC does not export construction vtable symbols from shared libraries.
The symbols are marked hidden in the objects; for Darwin that makes
them also external (“private_extern” is Darwin’s hidden) which means
that they show up in the list of possible symbols for export from
libstdc++, and there are sufficiently relaxed match conditions that
they reach the exports list. When Darwin’s static linker encounters
them it generates a warning that they cannot be exported. This patch
prunes them from the list of symbols to be considered, thus
eliminating the warnings. No functional Change inended to the library

asm inline
The Linux kernel people want a feature that makes GCC pretend some
inline assembler code is tiny (while it would think it is huge), so
that such code will be inlined essentially always instead of
essentially never.
This patch lets you say "asm inline" instead of just "asm", with the
result that that inline assembler is always counted as minimum cost
for inlining. It implements this for C and C++, making "inline"
another asm-qualifier (supplementing "volatile" and "goto").
