Subject: [PATCH] internal-fn,vect: Refactor widen_plus as internal_fn
DEF_INTERNAL_WIDENING_OPTAB_FN and DEF_INTERNAL_NARROWING_OPTAB_FN
are like DEF_INTERNAL_SIGNED_OPTAB_FN and DEF_INTERNAL_OPTAB_FN
respectively. With the exception that they provide convenience wrappers
for a single vector to vector conversion, a hi/lo split or an even/odd
split. Each definition for <NAME> will require either signed optabs
named <UOPTAB> and <SOPTAB> (for widening) or a single <OPTAB> (for
narrowing) for each of the five functions it creates.
