Missed opportunity to use [SU]ABD
This adds a recognition pattern for the non-widening
absolute difference (ABD).
gcc/ChangeLog:
* doc/md.texi (sabd, uabd): Document them.
* internal-fn.def (ABD): Use new optab.
* optabs.def (sabd_optab, uabd_optab): New optabs,
* tree-vect-patterns.cc (vect_recog_absolute_difference):
Recognize the following idiom abs (a - b).
(vect_recog_sad_pattern): Refactor to use
vect_recog_absolute_difference.
(vect_recog_abd_pattern): Use patterns found by
vect_recog_absolute_difference to build a new ABD
internal call.
