Mid engine setup [SU]ABDL
This updates vect_recog_abd_pattern to recognize the widening
variant of absolute difference (ABDL, ABDL2).
gcc/ChangeLog:
* internal-fn.def (VEC_WIDEN_ABD): New internal hilo optab.
* optabs.def (vec_widen_sabd_optab,
vec_widen_sabd_hi_optab, vec_widen_sabd_lo_optab,
vec_widen_sabd_odd_even, vec_widen_sabd_even_optab,
vec_widen_uabd_optab,
vec_widen_uabd_hi_optab, vec_widen_uabd_lo_optab,
vec_widen_uabd_odd_even, vec_widen_uabd_even_optab):
New optabs.
* doc/md.texi: Document them.
* tree-vect-patterns.cc (vect_recog_abd_pattern): Update to
to build a VEC_WIDEN_ABD call if the input precision is smaller
than the precision of the output.
(vect_recog_widen_abd_pattern): Should an ABD expression be
found preceeding an extension, replace the two with a
VEC_WIDEN_ABD.
