Optimization passes found a bug in the frontend regarding constants. Specifically in the case of instructions that have a 32bit constant that are sign extended to 64bit was being incorrectly set to have a size of 32bits (the size of the constant). So an optimization pass would rematerialize constants of the expected size, thus ~0ULL would turn in to ~0U and generate invalid code. Now watch the destination size and set the constant to that size, which matches what its size will be.
