394781b660 * Convert InstWorkList to vector instead of set, because on big programs it
is empirically faster by a noticable margin, even though duplicates can
  happen.

66ff017174 * Eliminate dead code that should have been removed in last revision
* Convert main constant propogation pass to be worklist driven instead of
  iterative.
* -constprop pass no longer "constant propogates" terminator instructions
   - CFG is now preserved!

910ca80941 * Use simplified interface to constant propogation stuff.
* Remove dead PHI case (which could not work due to getNumOperands rather than
  getNumIncomingValues.  This really belongs in InstCombine, anyway so we'll
  move it there.
