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.

don't use isPointerType()

* 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>(..)
