[ARM] Fix NEON failure introduced by D71065.

I rewrote the isel tablegen for MVE immediate shifts, and accidentally
removed the `let Predicates=[HasMVEInt]` that was wrapping the old
version, which seems to have allowed those rules to cause trouble on
non-MVE targets. That's what I get for only re-running the MVE tests.
