Richard Henderson 428dd03f5a Remove HP_TIMING_DIFF_INIT and dl_hp_timing_overhead 
Without HP_TIMING_ACCUM, dl_hp_timing_overhead is write-only.
If we remove it, there's no point in HP_TIMING_DIFF_INIT either.

Igor Zamyatin 2d63a517e4 Save and restore AVX-512 zmm registers to x86-64 ld.so 
AVX-512 ISA adds 512-bit zmm registers.  This patch updates
_dl_runtime_profile to pass zmm registers to run-time audit. It also
changes _dl_x86_64_save_sse and _dl_x86_64_restore_sse to upport zmm
registers, which are called when only when RTLD_PREPARE_FOREIGN_CALL
is used.  Its performance impact is minimum.

Ulrich Drepper e83c1a8a72 Refine testing for xmm/ymm register use in x86-64 ld.so. 
The test now takes the callgraph into account.  Only code called
during runtime relocation is affected by the limitation.  We now
determine the affected object files as closely as possible from
the outside.  This allowed to remove some the specializations
for some of the string functions as they are only used in other
code paths.

Ulrich Drepper 16d2ea4c82 Make sure no code in ld.so uses xmm/ymm registers on x86-64. 
This patch introduces a test to make sure no function modifies the
xmm/ymm registers.  With the exception of the auditing functions.

The test is probably too pessimistic.  All code linked into ld.so
is checked.  Perhaps at some point the callgraph starting from
_dl_fixup and _dl_profile_fixup is checked and we can start using
faster SSE-using functions in parts of ld.so.
