These checks already exist as asserts when creating the corresponding instruction. Anybody creating these instructions already need to take care to not break these checks. Move the checks for success/failure ordering in cmpxchg from the verifier to the LLParser and BitcodeReader plus an assert. Add some tests for cmpxchg ordering. The .bc files are created from the .ll files with an llvm-as with these checks disabled. Reviewed By: dblaikie Differential Revision: https://reviews.llvm.org/D102803
