H.J. Lu 0b5395f052 Update x86_64 multiarch functions for <cpu-features.h>
This patch updates x86_64 multiarch functions to use the newly defined
HAS_CPU_FEATURE, HAS_ARCH_FEATURE and LOAD_RTLD_GLOBAL_RO_RDX from
<cpu-features.h>.

	* sysdeps/x86_64/fpu/multiarch/e_asin.c: Replace HAS_XXX with
	HAS_CPU_FEATURE/HAS_ARCH_FEATURE (XXX).
	* sysdeps/x86_64/fpu/multiarch/e_atan2.c: Likewise.
