Elliot Colp b22cfb7859 [SystemZ] Remove AND mask of bottom 6 bits when result is used for shift/rotate ...

On SystemZ, shift and rotate instructions only use the bottom 6 bits of the shift/rotate amount.
Therefore, if the amount is ANDed with an immediate mask that has all of the bottom 6 bits set, we
can remove the AND operation entirely.
