Sander de Smalen 699e22a083 [ISEL] Move trivial step_vector folds to FoldConstantArithmetic. ...

helps with DAGCombine folds that happen before type legalization.

There is currently no way to test this happens earlier, although existing
tests for step_vector folds continue protect the folds happening at all.
