PR target/80846
* optabs.def (vec_extract_optab, vec_init_optab): Change from
a direct optab to conversion optab.
* optabs.c (expand_vector_broadcast): Use convert_optab_handler
with GET_MODE_INNER as last argument instead of optab_handler.
* expmed.c (extract_bit_field_1): Likewise. Use vector from
vector extraction if possible and optab is available.
* expr.c (store_constructor): Use convert_optab_handler instead
of optab_handler. Use vector initialization from smaller
vectors if possible and optab is available.
* tree-vect-stmts.c (vectorizable_load): Likewise.
* doc/md.texi (vec_extract, vec_init): Document that the optabs
now have two modes.
* config/i386/i386.c (ix86_expand_vector_init): Handle expansion
of vec_init from half-sized vectors with the same element mode.
* config/i386/sse.md (ssehalfvecmode): Add V4TI case.
(ssehalfvecmodelower, ssescalarmodelower): New mode attributes.
