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.

	* config.h.in (HAVE_AVX512_SUPPORT): New #undef.
	(HAVE_AVX512_ASM_SUPPORT): Likewise.
	* sysdeps/x86_64/bits/link.h (La_x86_64_zmm): New.
	(La_x86_64_vector): Add zmm.
	* sysdeps/x86_64/Makefile (tests): Add tst-audit10.
	(modules-names): Add tst-auditmod10a and tst-auditmod10b.
	($(objpfx)tst-audit10): New target.
	($(objpfx)tst-audit10.out): Likewise.
	(tst-audit10-ENV): New.
	(AVX512-CFLAGS): Likewise.
	(CFLAGS-tst-audit10.c): Likewise.
	(CFLAGS-tst-auditmod10a.c): Likewise.
	(CFLAGS-tst-auditmod10b.c): Likewise.
	* sysdeps/x86_64/configure.ac: Set config-cflags-avx512,
	HAVE_AVX512_SUPPORT and HAVE_AVX512_ASM_SUPPORT.
	* sysdeps/x86_64/configure: Regenerated.
	* sysdeps/x86_64/dl-trampoline.S (_dl_runtime_profile): Add
	AVX-512 zmm register support.
	(_dl_x86_64_save_sse): Likewise.
	(_dl_x86_64_restore_sse): Likewise.
	* sysdeps/x86_64/dl-trampoline.h: Updated to support different
	size vector registers.
	* sysdeps/x86_64/link-defines.sym (YMM_SIZE): New.
	(ZMM_SIZE): Likewise.
	* sysdeps/x86_64/tst-audit10.c: New file.
	* sysdeps/x86_64/tst-auditmod10a.c: Likewise.
	* sysdeps/x86_64/tst-auditmod10b.c: Likewise.
