H.J. Lu 72771e5375 x86: Use _rdtsc intrinsic for HP_TIMING_NOW 
Since _rdtsc intrinsic is supported in GCC 4.9, we can use it for
HP_TIMING_NOW.  This patch

1. Create x86 hp-timing.h to replace i686 and x86_64 hp-timing.h.
2. Move MINIMUM_ISA from init-arch.h to isa.h so that x86 hp-timing.h
can check minimum x86 ISA to decide if _rdtsc can be used.

NB: Checking if __i686__ isn't sufficient since __i686__ may not be
defined when building for i686 class processors.

	* sysdeps/i386/init-arch.h: Removed.
	* sysdeps/i386/i586/init-arch.h: Likewise.
	* sysdeps/i386/i686/init-arch.h: Likewise.
	* sysdeps/i386/i686/hp-timing.h: Likewise.
	* sysdeps/x86_64/hp-timing.h: Likewise.
	* sysdeps/i386/isa.h: New file.
	* sysdeps/i386/i586/isa.h: Likewise.
	* sysdeps/i386/i686/isa.h: Likewise.
	* sysdeps/x86_64/isa.h: Likewise.
	* sysdeps/x86/hp-timing.h: New file.
	* sysdeps/x86/init-arch.h: Include <isa.h>.
