[PATCH] D47681: [DAGCombiner] Bug 31275- Extract a shift from a constant mul or udiv if a rotate can be formed

It seems everyone else is busy with other differentials, and don't have time to spare to review this :/

Have you run this on a llvm test suite?

I don't have further comments, and i could accept this, **if** testsuite passes,
but it would be more comfortable if someone else could review this, too.
