The Profile Mode extension is not used by anybody, nor maintained by
anybody. The containers do not support the full API specified in recent
standards, and so enabling Profile Mode is not source compatible with

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.

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).

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.
