x86_64: Replace AVX512F .byte sequences with instructions
Since binutils 2.25 or later is required to build glibc, we can replace AVX512F .byte sequences with AVX512F instructions. Tested on x86-64 and x32. There are no code differences in libmvec.so and libmvec.a. * sysdeps/x86_64/fpu/svml_d_sincos8_core.S: Replace AVX512F .byte sequences with AVX512F instructions. * sysdeps/x86_64/fpu/svml_d_wrapper_impl.h: Likewise. * sysdeps/x86_64/fpu/svml_s_sincosf16_core.S: Likewise. * sysdeps/x86_64/fpu/svml_s_wrapper_impl.h: Likewise. * sysdeps/x86_64/fpu/multiarch/svml_d_sincos8_core_avx512.S: Likewise. * sysdeps/x86_64/fpu/multiarch/svml_s_sincosf16_core_avx512.S: Likewise.
