Philip Reames 4760eefc51 [X86] Updated target specific selection dag code to conservatively check for isAtomic in addition to isVolatile ...

See D66309 for context.

This is the first sweep of x86 target specific code to add isAtomic bailouts where appropriate. The intention here is to have the switch from AtomicSDNode to LoadSDNode/StoreSDNode be close to NFC; that is, I'm not looking to allow additional optimizations at this time.

Sorry for the lack of tests.  As discussed in the review, most of these are vector tests (for which atomicity is not well defined) and I couldn't figure out to exercise the anyextend cases which aren't vector specific.
