IntToPtr and PtrToInt instructions are basically no-ops that we can handle as such. In order to generate them properly as parameters we had to improve the ScopExpander, though the change is the first in the direction of a more aggressive scalar synthetization. This patch was originally contributed by Johannes Doerfert in r271888, but was in conflict with the revert in r272483. This is a recommit with some minor adjustment to the test cases to take care of differing instruction names. llvm-svn: 272485
