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.
