This patch removes the assumption propagation that was added in D110655 primarily to get assumption informatino on opaque call sites for optimizations. The analysis done in D111445 allows us to do this more intelligently in the back-end. Depends on D111445 Reviewed By: jdoerfert Differential Revision: https://reviews.llvm.org/D111463
