Quentin Colombet 0206b30ea6 [DAGCombiner] PCMP* sets its result to all ones or zeros so we can AND with the 
shifted mask rather than masking and shifting separately.

The patch adds this transformation to the DAGCombiner:

  (shl (and (setcc:i8v16 ...) N01C) N1C) -> (and (setcc:i8v16 ...) N01C<<N1C)
