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. * sysdeps/x86_64/fpu/multiarch/e_exp.c: Likewise. * sysdeps/x86_64/fpu/multiarch/e_log.c: Likewise. * sysdeps/x86_64/fpu/multiarch/e_pow.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_atan.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_fma.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_fmaf.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_sin.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_tan.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_ceil.S: Use LOAD_RTLD_GLOBAL_RO_RDX and HAS_CPU_FEATURE (SSE4_1). * sysdeps/x86_64/fpu/multiarch/s_ceilf.S: Likewise. * sysdeps/x86_64/fpu/multiarch/s_floor.S: Likewise. * sysdeps/x86_64/fpu/multiarch/s_floorf.S: Likewise. * sysdeps/x86_64/fpu/multiarch/s_nearbyint.S : Likewise. * sysdeps/x86_64/fpu/multiarch/s_nearbyintf.S: Likewise. * sysdeps/x86_64/fpu/multiarch/s_rintf.S: Likewise. * sysdeps/x86_64/fpu/multiarch/s_rintf.S : Likewise. * sysdeps/x86_64/multiarch/ifunc-impl-list.c: Likewise. * sysdeps/x86_64/multiarch/sched_cpucount.c: Likewise. * sysdeps/x86_64/multiarch/strstr.c: Likewise. * sysdeps/x86_64/multiarch/memmove.c: Likewise. * sysdeps/x86_64/multiarch/memmove_chk.c: Likewise. * sysdeps/x86_64/multiarch/test-multiarch.c: Likewise. * sysdeps/x86_64/multiarch/memcmp.S: Remove __init_cpu_features call.
