Fix bug, when rdpid intrinsic used eax instead of rax in 64bit mode. Ok for trunk?

gcc/
	* config/i386/i386.c (ix86_expand_builtin): Handle IX86_BUILTIN_RDPID.
	* config/i386/i386.md (rdpid_rex64) New.
	(rdpid): Make 32bit only.

gcc/testsuite/
	* gcc.target/i386/rdpid.c: Remove "eax".

Thanks,
Julia
