re PR tree-optimization/91940 (__builtin_bswap16 loop optimization)
PR tree-optimization/91940
* tree-vect-patterns.c: Include tree-vector-builder.h and
vec-perm-indices.h.
(vect_recog_rotate_pattern): Also handle __builtin_bswap16, either by
unpromoting the argument back to uint16_t, or by converting into a
rotate, or into shifts plus ior.
* gcc.dg/vect/vect-bswap16.c: Add -msse4 on x86, run on all targets,
expect vectorized 1 loops message on both vect_bswap and sse4_runtime
targets.
* gcc.dg/vect/vect-bswap16a.c: New test.
