* Convert main constant propogation pass to be worklist driven instead of
  iterative.
* -constprop pass no longer "constant propogates" terminator instructions

Use DIE instead of DCE anyway

Move code out of header file

* 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.

* Remove isPointerType, isMethodType, etc... methods.  Use isa<> instead
* Added specialization of isa for pointer types so that DerivedTypes.h doesn't
  have to be #included to use isa<PointerType>(..)
