Rewrite patterns to assume that the operand of STEP_VECTOR is a constant. The old patterns will stop working when the operand is changed from a Constant to a TargetConstant.  (See D105673 <https://reviews.llvm.org/D105673>.)

Add test coverage for certain patterns that weren't exercised by existing regression tests.
