PR libstdc++/81266 fix std::thread::native_handle_type test
The test uses remove_pointer because in most cases native_handle_type is
a pointer to the actual type that the C++ class contains. However, for
std::thread, native_handle_type is the same type as the type contained
in std::thread, and so remove_pointer is not needed. On targets where
pthread_t is a pointer type remove_pointer<native_handle_type> is not a
no-op, instead it transforms pthread_t and causes the test to fail.
The fix is to not apply remove_pointer when testing std::thread.

compiler: avoid copy for string([]byte) conversion used in map keys
If a string([]byte) conversion is used immediately as a key for a
map read, we don't need to copy the backing store of the byte
slice, as mapaccess does not keep a reference to it.
The gc compiler does more than this: it also avoids the copy if
the map key is a composite literal that contains the conversion
as a field, like, T{ ... { ..., string(b), ... }, ... }. For now,
we just optimize the simple case, which is probably most common.

an issue with the patch I committed previously to improve the code
generation when pushing high registers, in that
thumb_find_work_register had a different idea as to which registers
were available as scratch registers.
The new code actually does a better job of finding a viable work
register and doesn't rely so much on assumptions about the ABI, so it
seems better to adapt thumb_find_work_register to the new approach.
This way we can eliminate some rather crufty code.

The recent trunk r270914 for PR89221 "--enable-frame-pointer does not work as

This has the side effect that, for example, for '--target=i686-gnu' this is now
enabled by default: 'USE_IX86_FRAME_POINTER=1' is added to 'tm_defines'. Given
that it's highly unlikely that anyone would now suddenly want

[RS6000] PR89271, gcc.target/powerpc/vsx-simode2.c
This patch makes a number of corrections to rs6000_register_move_cost,
adds a new register union class, GEN_OR_VSX_REGS, and adjusts insn
alternative costs to suit.
The patch initially just corrected register move cost when direct
moves are available, but that resulted in regressions. Inspection of
those regressions showed ALL_REGS being used as the register allocno
class, which isn't ideal. gcc/doc/tm.texi says: "You should define a
class for the union of two classes whenever some instruction allows
both classes". Thus, define GEN_OR_VSX_REGS for the register
allocator. (IRA wants to use the union of two register classes when
the costs of the classes are below memory cost, which happens more
often with the low direct move cost.)
As per https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89271#c11 we ought
to be returning the minimal cost for union classes. That can be done
by rs6000_register_move_cost testing for vsx first, where the number
of regs for a given mode might be smaller than the same mode in gprs,
and changing the LINK_OR_CTR_REGS case to exclude SPEC_OR_GEN_REGS and
NON_FLOAT_REGS.
I removed the VECTOR_MEM_VSX_P test since that leads to silly results
for scalar mode moves between altivec and float when TARGET_VSX. eg.
rs6000_register_move_cost:, ret=2, mode=DF, from=FLOAT_REGS, to=FLOAT_REGS
rs6000_register_move_cost:, ret=16, mode=DF, from=FLOAT_REGS, to=ALTIVEC_REGS
rs6000_register_move_cost:, ret=2, mode=DF, from=FLOAT_REGS, to=VSX_REGS
The patch also fixes wrong results for moves within and between any of
the non-gpr, non-vsx special reg classes. The comment about "moving
between two similar registers is just one instruction" is false. We
can't move lr to ctr directly, for example. I believe the intent of
the "reg_classes_intersect_p (to, from)" was to cover moves within
float or altivec, so I moved that test inside the code handling vsx,
and made sure the intersection wasn't anything besides vsx by masking
off everything else. Masking isn't strictly necessary at the moment,
but would be if we create a GEN_OR_ALTIVEC_REGS class some time in the
future.
TARGET_IRA_CHANGE_PSEUDO_ALLOCNO_CLASS is needed for rs6000 in order
to fix the 20% cactus_adm spec regression when using GEN_OR_VSX_REGS
as an allocno class. It is similar to the aarch64 version but without
any selection by regno mode if the best class is a union class.

This patch fixes a problem with the thumb1 prologue code where the link
register could be unconditionally used as a scratch register even if the
return value was still live at the end of the prologue.
Additionally, the patch improves the code generated when we are not
using many low call-saved registers to make use of any unused call
clobbered registers to help with the saving of high registers that
cannot be pushed directly (quite rare in normal code as the register
allocator correctly prefers low registers).

PR libstdc++/89102 implement new common_type rules (P0435R1, P0548R1)
This change ensures that std::common_type<> is a complete type (LWG
2408), and that std::common_type<T>, std::common_type<cv T1, cv T2>, and
std::common_type<T1, T2, R...> will use program-defined specializations
for std::common_type<T1, T2> (LWG 2465).
The implementation of common_type<T1, T2, R...> is changed to use
void_t, and the specializations for duration and time_point are modified
to also use void_t instead of depending on implementation details of
common_type.

rs6000: Renumber the registers
This renumbers the registers.
It moves the VRs to 64..95, right after the GPRs and the FPRS. This
means that the VSRs (which are aliases to the FPRs and the VRs, in
that order) are consecutive now.
It removes MQ, which has been just a stub for ages (it is a leftover
from RIOS, old POWER).
It moves the CR fields to 100..107, which is a bit easier to read
than the 68..75 is was before.
The rest fills the holes. It should be easy to move anything else
after this series, so the exact order isn't very important anymore,
we aren't stuck with it if we dislike it.
Many things still want the GPRs to be at 0..31, and some things want
the FPRs at 32..63. I don't think we'll ever want to change that,
so I left it be.
Small things... It removes DWARF_FRAME_REGISTERS, it used to save
1000 or so words of memory, but it has been just a handful for a
while, and now it is one. Some whitespace fixes. Testing showed one
or two places where register allocation was different (not worse, not
better, just different).

rs6000: Remove TM regs
We do not need to expose the TM registers in debug info. It isn't
actually useful there, because none of the things that can modify
these registers (other than explicit moves) are marked.
We also do not need the registers for GCC itself internally. This
patch deletes them.

rs6000: rs6000_dbx_register_number for fp/ap/mq
The frame pointer and the argument pointer aren't real registers. MQ
was a register on old POWER. All three are still used as arguments to
rs6000_dbx_register_number during initialisation. If we handle them
explicitly we can do a gcc_unreachable to catch other unexpected
registers.
