This tremendously improves the code generated by the LLVM optimizer, primarily
by making the inliner more aggressive.  For example, it improves the stepanov
benchmark from 55.56 mega-additions/sec to 98.04 Ma/s.  It also improves the
oopack/iterator benchmark from 338.3MFLOPS/s to 1103.4MFLOPS/s.  Less noteworthy,
it improves oopack/matrix from 573 -> 641 MFLOPS/s.

FP_REG_KILL instructions at the end of blocks involved with critical edges.

Fix a bug where FP_REG_KILL instructions weren't inserted in fall through
unconditional branches.  Perhaps this will fix some linscan problems?
