GlobalISel: Add assert that legalize mutation makes sense

I've repeatedly encountered bugs resulting from custom legalize
mutations returning nonsense legalize results, such as increasing the
number of elements for FewerElements. Add an assert function to make
sure the type to mutate to is consistent with the legalize action.
