[DAGCombiner] Bug 31275- Extract a shift from a constant mul or udiv if a rotate can be formed
Summary:
Attempt to extract a shrl from a udiv or a shl from a mul if this allows a rotate to be formed. This targets cases where the input to a rotate pattern was a mul or udiv by a constant and InstCombine merged one of the shifts with the op.
