  AtomicExpand: Change return type for shouldExpandAtomicStoreInIR

Use the same enum as the other atomic instructions for consistency, in
preparation for addition of another strategy.

Introduce a new "Expand" option, since the store expansion does not
use cmpxchg. Alternatively, the existing CmpXChg strategy could be
renamed to Expand.
