[PATCH] D129995: [AArch64] isDesirableToCommuteWithShift - fix UBFX masked shift comment. NFC.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

isDesirableToCommuteWithShift should only ever be called from a shift instruction - it wasn't planned to work the other way as well - I'd be happy to add asserts to the calls like we (mostly) have for shouldFoldConstantShiftPairToMask?
