Cherry Zhang 7846500a5a cmd/compile: remove redundant constant shift rules ... Normal shift rules plus constant folding are enough to generate efficient shift-by-constant instructions. Add test to make sure we don't generate comparisons for constant shifts. TODO: there are still constant shift rules on PPC64. If they are removed, the constant folding rules are not enough to remove all the test and mask stuff for constant shifts. Leave them in for now. Fixes #20663.
