x86: Don't include <x86intrin.h>
Use __builtin_ia32_rdtsc directly since including <x86intrin.h> makes building glibc very slow. On Intel Core i5-6260U, this patch reduces x86-64 build time from 8 minutes 33 seconds to 3 minutes 48 seconds with "make -j4" and GCC 8.2.1. * sysdeps/x86/hp-timing.h: Don't include <x86intrin.h>. (HP_TIMING_NOW): Replace _rdtsc with __builtin_ia32_rdtsc.
