iAs listed in the summary D77846, we have 5 different categories of bugs we're checking for in CallAndMessage. I think the documentation placed in the code explains my thought process behind my decisions quite well. A non-obvious change I had here is removing the entry for CallAndMessageUnInitRefArg. In fact, I removed the CheckerNameRef typed field back in D77845 (it was dead code), so that checker didn't really exist in any meaningful way anyways.
