Jung-uk Kim 5df88f46bb Teach the compiler how to shift TSC value efficiently. As noted in r220631,
some times compiler inserts redundant instructions to preserve unused upper
32 bits even when it is casted to a 32-bit value.  Unfortunately, it seems
the problem becomes more serious when it is shifted, especially on amd64.
