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.
