Max Kazantsev 6ac04e25a3 [InstCombine] Delay foldICmpUsingKnownBits until simple transforms are done ...

This patch changes order of transform in InstCombineCompares to avoid
performing transforms based on ranges which produce complex bit arithmetics
before more simple things (like folding with constants) are done. See PR37636
for the motivating example.
