0d09ca2550 Remove array_allocator extension, deprecated since 4.9.0
This type is not a conforming allocator, because it cannot be reliably
rebound to allocate for a different type. The result of the rebind
transformation still uses the same underlying std::tr1::array<T, 1>
array, which may not be correctly aligned or even have elements the
right size for the value_type of the rebound allocator.

It has been deprecated for several years and should now be removed.

ef5eb79dfd darwin, powerpc - set .machine in an asm file.

0f8768f734 x86 - fix pr82920
The various thunks output codes have inconsisten output
mechanisms. The patch factors out some common code that
writes out the jumps and uses the regular output scheme
that accounts for __USER_LABEL_PREFIX__.

The testsuite changes are largely mechanical compensation
for the revised output (and the fact that Darwin doesn't
use non-PIC by default).

1a1e427caa PR libstdc++/81266 fix std:🧵: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.

8743680541 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.

4456525c4e [arm] PR target/90405 fix regression for thumb1 with -mtpcs-leaf-frame
-mtpcs-leaf-frame causes an APCS-style backtrace frame to be created
on the stack.  This should probably be deprecated, but it did reveal
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.
