[PATCH] D65803: [MVE] Don't try to unroll vectorised MVE loops

Hey. I'm not sure I see what you mean. Surely if unrolling cause changes that were illegal from a tail predication point of view, we would need to not do tail predication! (i.e you can manually unroll a loop and produce similar code).

These changes are aimed at performance though. For any loop that we are not tail-predicating, we should still prefer to not unroll it.
