H.J. Lu 1aee37a22e Update i686 multiarch functions for <cpu-features.h>
This patch updates i686 multiarch functions to use the newly defined
HAS_CPU_FEATURE, HAS_ARCH_FEATURE, LOAD_GOT_AND_RTLD_GLOBAL_RO and
LOAD_FUNC_GOT_EAX from <cpu-features.h>.

	* sysdeps/i386/i686/fpu/multiarch/e_expf.c: Replace HAS_XXX
	with HAS_CPU_FEATURE/HAS_ARCH_FEATURE (XXX).
	* sysdeps/i386/i686/fpu/multiarch/s_cosf.c: Likewise.

	* sysdeps/i386/i686/multiarch/bcopy.S: Remove __init_cpu_features
	call.  Merge SHARED and !SHARED.  Add LOAD_GOT_AND_RTLD_GLOBAL_RO.
	Use LOAD_FUNC_GOT_EAX to load function address.  Replace HAS_XXX
	with HAS_CPU_FEATURE/HAS_ARCH_FEATURE (XXX).
