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/fpu/multiarch/s_cosf.c: Likewise. * sysdeps/i386/i686/fpu/multiarch/s_sincosf.c: Likewise. * sysdeps/i386/i686/fpu/multiarch/s_sinf.c: Likewise. * sysdeps/i386/i686/multiarch/ifunc-impl-list.c: Likewise. * sysdeps/i386/i686/multiarch/s_fma.c: Likewise. * sysdeps/i386/i686/multiarch/s_fmaf.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.
