The can_vec_perm_p interface changed to use a C integer array.  This
allows easy re-use from the rtl level and the gimple level within
the vectorizer.  It allows both to determine if a given permutation
is (un-)supported without having to create tree/rtl garbage.

re-use from the rtl level, so that expand_vec_perm can be used in the
fallback implementation of other optabs.
