H.J. Lu 3403a17fea x86-64: Verify that _dl_runtime_resolve preserves vector registers
On x86-64, _dl_runtime_resolve must preserve the first 8 vector
registers.  Add 3 _dl_runtime_resolve tests to verify that SSE,
AVX and AVX512 registers are preserved.

	* sysdeps/x86_64/Makefile (tests): Add tst-sse, tst-avx and
	tst-avx512.
	(test-extras): Add tst-avx-aux and tst-avx512-aux.
	(extra-test-objs): Add tst-avx-aux.o and tst-avx512-aux.o.
	(modules-names): Add tst-ssemod, tst-avxmod and tst-avx512mod.
	($(objpfx)tst-sse): New rule.
	($(objpfx)tst-avx): Likewise.
	($(objpfx)tst-avx512): Likewise.
	(CFLAGS-tst-avx-aux.c): New.
	(CFLAGS-tst-avxmod.c): Likewise.
	(CFLAGS-tst-avx512-aux.c): Likewise.
	(CFLAGS-tst-avx512mod.c): Likewise.
	* sysdeps/x86_64/tst-avx-aux.c: New file.
	* sysdeps/x86_64/tst-avx.c: Likewise.
	* sysdeps/x86_64/tst-avx512-aux.c: Likewise.

	* sysdeps/x86_64/tst-sse.c: Likewise.
	* sysdeps/x86_64/tst-ssemod.c: Likewise.
