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-avx512.c: Likewise. * sysdeps/x86_64/tst-avx512mod.c: Likewise. * sysdeps/x86_64/tst-avxmod.c: Likewise. * sysdeps/x86_64/tst-sse.c: Likewise. * sysdeps/x86_64/tst-ssemod.c: Likewise.
