The asm file fails to build if we use a modern assembler
which checks that the machine is consistent with the

other assembler.

The recent AArch64 absolute difference patterns had to go through
some hoops to pair max/min rtx codes with the same signedness.
I also need to pair signed/unsigned codes with sign/zero extension
for some SVE ACLE patterns.
This patch therefore supports <...> as rtx codes, like we already
do for modes.

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.

A disabled specialization should not be callable, so move the function
call operator into a new base class which correctly implements the
disabled hash semantics. For the versioned namespace configuration do
not derive from __poison_hash in the enabled case, as the empty base
class serves no purpose but potentially increases the object size. For
the default configuration that base class must be kept, to preserve
layout.
An enabled specialization should not be unconditionally noexcept,
because the underlying hash object might throw.

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.

-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.
