Unconditionally removing landing pads results in invalid IR, if there is a different `invoke` that uses it. Update the code to only remove the landing pad if the current invoke is the only user. Also carefully avoid creating plain branches to bbs with landing pads we couldn't remove. Reviewed By: arsenm, aeubanks Differential Revision: https://reviews.llvm.org/D138072
