544be2beb1 Remove Profile Mode, deprecated since GCC 7.1
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
much modern C++ code. The heuristics that would check the profile
information and make useful suggestions never materialized, so it isn't
useful.

It should be removed.

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.

The various thunks output codes have inconsisten output
mechanisms. The patch factors out some common code that

that accounts for __USER_LABEL_PREFIX__.

The testsuite changes are largely mechanical compensation

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.
