Eli Friedman 7c5dc122a0 Change a bunch of isVolatile() checks to check for atomic load/store as well. ...

No tests; these changes aren't really interesting in the sense that the logic is the same for volatile and atomic.

I believe this completes all of the changes necessary for the optimizer to handle loads and stores correctly.  I'm going to try and come up with some additional testing, though.
