* Rewrite cast->cast elimination code completely based on the information weChris Lattner2004-07-201-43/+53
| | | | | | | | actually care about. Someday when the cast instruction is gone, we can do better here, but this will do for now. This implements instcombine/cast.ll:test17/18 as well. llvm-svn: 15018
