gvn/gcm review

- Many stylistic nits.
- Removed blkmerge().
- Some minor bug fixes.
- GCM reassoc is now "sink"; a pass that
  moves trivial ops in their target block
  with the same goal of reducing register
  pressure, but starting from instructions
  that benefit from having their inputs
  close.
