[nvptx] Force vl32 if calling vector-partitionable routines
With PTX_MAX_VECTOR_LENGTH set to larger than PTX_WARP_SIZE, routines can be
called from offloading regions with vector-size set to larger than warp size.
OTOH, vector-partitionable routines assume warp-sized vector length.
Detect if we're calling a vector-partitionable routine from an offloading
region, and if so, fall back to warp-sized vector length in that region.

[nvptx] Don't emit barriers for empty loops -- fix
When compiling an empty loop:
...
long long v1;
#pragma acc parallel num_gangs (640) num_workers(1) vector_length (128)
#pragma acc loop
for (v1 = 0; v1 < 20; v1 += 2)
;
...
the compiler emits two subsequent bar.syncs. This triggers some bug on my
quadro m1200 (I'm assuming in the ptxas/JIT compiler) that hangs the testcase.
This patch works around the bug by doing an optimization: we detect that this is
an empty loop (a forked immediately followed by a joining), and don't emit the
barriers.
The patch does not include the test-case yet, since vector_length (128) is not
yet supported at this point.

PR libstdc++/86756 Move rest of std::filesystem to libstdc++.so
Move std::filesystem directory iterators and operations from
libstdc++fs.a to main libstdc++ library. These components have many
dependencies on OS support, which is not available on all targets. Some
additional autoconf checks and conditional compilation is needed to
ensure the files will build for all targets. Previously this code was
not compiled without --enable-libstdcxx-filesystem-ts but the C++17
components should be available for all hosted builds.
The tests for these components no longer need to link to libstdc++fs.a,
but are not expected to pass on all targets. To avoid numerous failures
on targets which are not expected to pass the tests (due to missing OS
functionality) leave the dg-require-filesystem-ts directives in place
for now. This will ensure the tests only run for builds where the
filesystem-ts library is built, which presumably means some level of OS
support is present.

PR libstdc++/87431 fix regression introduced by r264574
The previous patch for PR 87431 assumed that initialing a scalar type
could not throw, but it can obtain its value via a conversion operator,
which could throw. This meant the variant could get into a valueless
state, but the valueless_by_exception() member function would always
return false.
This patch fixes it by changing the emplace members to have strong
exception safety when initializing a contained value of trivially
copyable type. The _M_valid() member gets a corresponding change to
always return true for trivially copyable types, not just scalar types.
Strong exception safety (i.e. never becoming valueless) is achieved by
only replacing the current contained value once any potentially throwing
operations have completed. If constructing the new contained value can
throw then a new std::variant object is constructed to hold it, and then
move-assigned to *this (which won't throw).
PR libstdc++/87431
* include/std/variant (_Variant_storage<true, _Types...>::_M_valid):
Check is_trivially_copyable instead of is_scalar.
(variant::emplace<N, Args>(Args&&...)): If construction of the new
contained value can throw and its type is trivially copyable then
construct into a temporary variant and move from it, to provide the
strong exception safety guarantee.

Likewise.

Add more testcases for class template argument deduction of maps
This adds additional tests for std::map and std::multimap CTAD. The
tests ensure that deduction works for braced-init-list of value_type
objects, and for pairs of input iterators (with both std::pair<Key, T>
and value_type as the iterator's value_type). This ensures deduction
from value_type still works, as well as the non-value_type cases in LWG
3025.
Similar tests for unordered maps do not work, apparently because the
constructor taking an initializer_list<value_type> is not usable for
deduction, and the deduction guide taking initializer_list<pair<Key, T>>
deduces key_type to be const. I am not addressing that.
