Adam Nemet 622f350944 [DAGCombiner] Slightly improve readability of matchRotateSub
Slightly change the wording in the function comment. Originally, it can be
misunderstood as we turned the input into two subsequent rotates.

Better connect the comment which talks about Mask and the code which used
LoBits.  Renamed variable to MaskLoBits.
