  -----------
  [mlir] Fix bug in use of rewiter for AtomicRMWOp.

The legalization did not forward the listener which prevents dynamic
legalization and prevents rollbacks. This handled that and then changed
the associated pass to support all other std ops to support partial
conversion.

Previously, this lowering was failing, but due to the
initial bug, the op's modifications were not reverted, and thus the
pattern matching succeeded.
