Save and restore AVX-512 zmm registers to x86-64 ld.so

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.
