Adjusted FAKE_MCOUNT()s for amd64. This is needed for both ordinary
and high resolution profiling of interrupt handlers. The adjustments
are routine once the magic stack offset 13*4 is decoded to be TF_RIP
(there were originally more types of stack frames so using TF_EIP for
one of them wouldn't have been much simpler).
Removed garbage comments attached to some of the FAKE_MCOUNT()s.
