Question for Reviewers: Going through uses of isVolatile in backend code, I see suspicious bits in Lania, ARM, and Hexagon. What's the best way to handle this? I can easily apply the workaround I mention for out of tree backends, or I could make them equally conservative for isAtomic. The other in tree backends appear to be fine, though I'd welcome review from folks knowledgeable of non-x86 backends.
