Most but not all of the tests that expect M_PI, M_PI_2 and/or M_PI_4
to be defined in math.h explicitly exclude one target system that does
not satisfy this non-standard assumption.

This patch introduces a wrapper header that includes math.h and then
conditionally supplies the missing non-standard macro definitions.
With that, we can drop the dg-skip-if "no M_PI" exclusions.

Here, since the call to g is not type-dependent, we call mark_used on it to
determine its return type.  This also wants to instantiate the
noexcept-expression.  But since nothing in maybe_instantiate_noexcept was
calling push_to_top_level, we substituted b.i with processing_template_decl
set, so we left it unresolved for later access checking.  As a result, the
type of C::g<int> remained instantiation-dependent, leading to an ICE in
type_dependent_expression_p on the assert that the type of a function
template with no dependent template arguments must be non-dependent.

Input string consist of four parts:

and generator doing combination with <extensions> part, but it just
append the extension at the end of arch string, it might generate
invalid arch.

For example, without this patch `./multilib-generator rv32imafc-ilp32--d`
will generate:

MULTILIB_OPTIONS = march=rv32imafc/march=rv32imafcd mabi=ilp32

This patch fixes PR c++/88095: class nontype template parameter UDL string
literals doesn't accepts deduction placeholder

It also addresses a latent issue; literal operator templates with template
parameter packs of literal class type were previously accepted.  The patch
corrects this and adds a test (udlit-class-nttp-neg.C).

This fix is needed for one of the char8_t remediation approaches documented
in P1423, and may be helpful for existing code bases impacted by the char8_t
changes adopted via P0482 for C++20.

Adding SVE intrinsics on top of the existing AArch64 intrinsics blows
the 12-bit function_code in tree_function_decl.  That bitfield has no
spare bits, but it comes at the end of the structure and is preceded
by a pointer, so on LP64 hosts there's currently a 32-bit hole at end.

This patch therefore makes function_code an independent field and
moves the bitfield to the 32-bit hole.

I wondered about instead making function_code 16 bits, so that the
patch leaves 28 spare bits instead of just 12.  That seemed a bit
short-term though; I can't guarantee that we won't blow 16 bits once
the SVE2 functions are added...

If we run out of bits again, we can start chomping from the top
of the enum.  E.g. 24 bits should surely be enough, but there's
no point paying the overhead of the masking until we need it.

This patch folds IFN_MASK_LOAD and IFN_MASK_STOREs to normal accesses
if the mask is all-true.  This can happen for fully-masked loops that
didn't actually need to be (which could be handled by the vectoriser
instead), or for unrolled fully-masked loops whose first iteration is
guaranteed to operate on a full vector.  It's also useful when the
accesses are generated directly by intrinsics (to follow for SVE).

I needed to add another instance of this idiom, so thought it'd
be worth having a helper function.

 - argument and return value for libcall won't promote at
   default_promote_function_mode_always_promote, however we expect it
   should sign-extend as normal function.

 - Witout this patch, this test case will fail at -march=rv64i -mabi=lp64.

 - The implementation of riscv_promote_function_mode is borrowed from MIPS.
