[LoopVectorizer][ARM] Add preferInloopReduction reduction.
Needs ReviewPublic

Authored by dmgreen on Mar 3 2020, 3:59 AM.



This allows the backend to tell the vectorizer to produce inloop reductions through a TTI hook.

For the moment on ARM under MVE this means allowing integer add reductions of the correct size. In the future this can include integer min/max too, under -Os. Taken out of D75069.
