OK. Now that D60708 <https://reviews.llvm.org/D60708> is in this is a rebase on what that became. Some of this patch has changed a little as a result and in getting +mve to work. It appears that +mve without a fp is currently broken, as it is add registers without making the operations illegal.

The changes to addMVEVectorTypes have also been moved here, because of how much they have changed. I also needed to fix an fp16 bug in one of the buildvector routines and added a couple of extra patterns.

The tests now test +mve,+fullfp16 and +mve.fp, but not yet +mve which can be added later once that works sensibly.
