Previously, we were just running ObjCARCContract when codegening. This is out of character with the rest of the LLVM passes in Swift, namely that after these have run, an IR pass no longer contains any compiler intrinsics. This can be seen by SwiftARCContract running in the -O pipeline. This commit harmonizes the behavior here. For testing purposes, I added a flag that disables the running of ObjCARCContract for testing purposes. rdar://34824507
