* config/i386/i386-expand.c (expand_vector_set_var):
Handle V2FS mode remapping. Pass TARGET_MMX_WITH_SSE to
ix86_expand_vector_init_duplicate.
(ix86_expand_vector_init_duplicate): Emit insv_1 for
QImode for !TARGET_PARTIAL_REG_STALL.
* config/i386/predicates.md (vec_setm_mmx_operand): New predicate.
* config/i386/mmx.md (vec_setv2sf): Use vec_setm_mmx_operand
as operand 2 predicate. Call ix86_expand_vector_set_var
for non-constant index operand.
(vec_setv2si): Ditto.
(vec_setv4hi): Ditto.
(vec_setv8qi): ditto.
