* config/i386/i386-expand.c (ix86_expand_vector_init_duplicate):
Handle V2HI mode.
(ix86_expand_vector_init_general): Ditto.
Use SImode instead of word_mode for logic operations
when GET_MODE_SIZE (mode) < UNITS_PER_WORD.
(expand_vec_perm_even_odd_1): Assert that V2HI mode should be
implemented by expand_vec_perm_1.
(expand_vec_perm_broadcast_1): Assert that V2HI and V4HI modes
should be implemented using standard shuffle patterns.
(ix86_vectorize_vec_perm_const): Handle V2HImode. Add V4HI and
V2HI modes to modes, implementable with shuffle for one operand.
* config/i386/mmx.md (*punpckwd): New insn_and_split pattern.
(*pshufw_1): New insn pattern.
(*vec_dupv2hi): Ditto.
(vec_initv2hihi): New expander.
