bool SelectionDAGISel::CheckAndMask ( SDValue  LHS,

int64_t  DesiredMaskS

CheckAndMask - The isel is trying to match something like (and X, 255).

If the dag combiner simplified the 255, we still want to match. RHS is the actual value in the DAG on the RHS of an AND, and DesiredMaskS is the value specified in the .td file (e.g. 255).
