Use VEC_PERM_EXPR in the vectorizer.
* tree-vect-slp.c: Include langhooks.h.
(vect_create_mask_and_perm): Emit VEC_PERM_EXPR, not a builtin.
(vect_transform_slp_perm_load): Use can_vec_perm_expr_p. Simplify
mask creation for VEC_PERM_EXPR.
* tree-vect-stmts.c (perm_mask_for_reverse): Return the mask,
not the builtin.
(reverse_vec_elements): Emit VEC_PERM_EXPR not a builtin.
* Makefile.in (tree-vect-slp.o): Update dependency.
* optabs.c (can_vec_perm_expr_p): Allow NULL as unknown constant.
