[NFC] `using namespace Abstract` to make matchers more compact (#3284)

This change makes matchers in OptimizeInstructions more compact and readable by
removing the explicit `Abstract::` namespace from individual operations. In some
cases, this makes multi-line matcher expressions fit on a single line.

This change is only possible because it also adds an explicit "RMW" prefix to
each element of the `AtomicRMWOp` enumeration. Without that, their names
conflicted with the names of Abstract ops.
