Andy Lutomirski 03b9730b76 x86/asm/tsc: Add rdtsc_ordered() and use it in trivial call sites 
rdtsc_barrier(); rdtsc() is an unnecessary mouthful and requires
more thought than should be necessary. Add an rdtsc_ordered()
helper and replace the trivial call sites with it.

This should not change generated code. The duplication of the
fence asm is temporary.
