PR c++/89089 - ICE with [[no_unique_address]].
In 89089, we were never actually setting DECL_SIZE on an empty data member,
because its type is a POD, so we didn't set it in the maybe-overlapping
section. Fixed by also handling empty types there.
In 88865, we were failing to consider empty data members in
include_empty_classes. Fixed by making end_of_class always include them.
While looking at these I noticed that the ABI says that a
potentially-overlapping data member makes its class non-layout-POD, and that
an empty data member doesn't prevent its class from being empty, so I've
implemented those points as well.

[libbacktrace] Don't assign check_PROGRAMS to TESTS
In automake files, the check_PROGRAMS variable lists programs that need to be
build for testing, and TESTS lists the programs that need to be run.
The libbacktrace/Makefile.am uses a shortcut:
...
TESTS = $(check_PROGRAMS)
...
to make sure that each program added with:
...
check_PROGRAMS += foo
...
is both build and run.
However, for the allocfail.sh test, we need allocfail to be build and
allocfail.sh to be run:
...
check_PROGRAMS += allocfail
TESTS += allocfail.sh
...
but the shortcut causes allocfail also to be run, which is not required.
Fix this by removing the short-cut, allowing check_PROGRAMS to retain its
original semantics, and introducing a variable BUILDTESTS for programs that
need to be both build and run.

runtime: use the call instruction's PC for panic-in-runtime detection
If a panic happens in the runtime we turn that into a fatal error.
We use the caller's PC to determine if the panic call is inside
the runtime. getcallerpc returns the PC immediately after the
call instruction. If the call is the very last instruction of a
function, it may not find this PC belong to a runtime function,
giving false result. We need to back off the PC by 1 to the call
instruction.
The gc runtime doesn't do this because the gc compiler always
emit an instruction following a panic call, presumably an UNDEF
instruction which turns into an architecture-specific illegal
instruction. Our compiler doesn't do this.

Ensure pool resources always use normal mode vector
The __pool_resource::_M_unpooled member was declared with type
std::vector, which means that the type depends on whether debug mode is
active or not. Because the non-inline definitions in
src/c++17/memory_resource.cc are never compiled with debug mode, the
type declared in the header doesn't match the type in the library
definitions, leading to undefined behaviour.
The solution is to ensure the header always uses the non-debug vector,
even when debug mode is active. To make this easier a new alias template
is defined: _GLIBCXX_STD_C::pmr::vector.

This is pretty unlikely in real code...
This is pretty unlikely in real code, but similar to Arm, the AArch64
ABI has a bug with the handling of 128-bit bit-fields, where if the
bit-field dominates the overall alignment the back-end code may end up
passing the argument correctly. This is a regression that started in
gcc-6 when the ABI support code was updated to support overaligned
types. The fix is very similar in concept to the Arm fix. 128-bit
bit-fields are fortunately extremely rare, so I'd be very surprised if
anyone has been bitten by this.

[AArch64][SVE] Handle register-register pred_movs
pred_mov<mode> is defined for predicated loads and stores, where
exactly one of the operands is a register. However, the instruction
condition only checked for "one" rather than "exactly one", and
Prathamesh found a case in which combine could fold a predicated
pattern to an all-register pred_mov<mode>. The constraints would
then force one of the registers to memory.
This patch splits all-register forms into a normal move as soon
as possible, but also adds an all-register alternative in case the
instruction doesn't get split before RA (or in case the RA can use
inheritance to avoid a reload).
The testcase for this will be added to aarch64/sve-acle-branch.

It used to be the case that the mangled name of a reference temporary didn't
need to be standardized, because all access would be through the reference.
But now constant expressions can look through references and so different
translation units need to agree on the address of a temporary in the
initializer of a reference with vague linkage.

Mitigation for PR target/88469 on arm-based systems bootstrapping with gcc-6/7/8
This patch, for gcc 8/9 is a mitigation patch for PR target/88469
where gcc-6/7/8 miscompile a structure whose alignment is dominated by
a 64-bit bitfield member. Since the PCS rules for such a type must
ignore any overalignment of the base type we cannot address this by
simply adding a larger alignment to the class. We can, however, force
the alignment of the bit-field itself and GCC will handle that as
desired.
