arm: Auto-vectorization for MVE and Neon: vhadd/vrhadd
This patch adds support for auto-vectorization of average value
computation using vhadd or vrhadd, for both MVE and Neon.
The patch adds the needed [u]avg<mode>3_[floor|ceil] patterns to
vec-common.md, I'm not sure how to factorize them without introducing
an unspec iterator?
It also adds tests for 'floor' and for 'ceil', each for MVE and Neon.
