Craig Topper 0428e2f205 [X86] Don't turn (and (shl X, C1), C2) into (shl (and X, (C1 >> C2), C2) if the original AND can represented by MOVZX. ...

The MOVZX doesn't require an immediate to be encoded at all. Though it does use
a 2 byte opcode so its the same size as a 1 byte immediate. But it has a
separate source and dest register so can help avoid copies.
