15 (neon_vec_<US>mult_lo_<mode>"): Instruction pattern for vmull.
16 (neon_vec_<US>mult_hi_<mode>"): Likewise.
17 (neon_unpack<US>_<mode>): Widening move intermediate step for
18 vectorizing without -mvectorize-with-neon-quad.
19 (neon_vec_<US>mult_<mode>): Widening multiply intermediate step
20 for vectorizing without -mvectorize-with-neon-quad.
21 * config/arm/predicates.md (vect_par_constant_high): Check for
22 high-half lanes of a vector.
