Something like:
(define_insn_and_split "altivec_dup<mode>"
[(set (match_operand:V 0 "register_operand" "v")
(vec_duplicate: (match_operand: 0 "r")))
(clobber (match_operand:V 3 "memory_operand" "=Z"))]
"TARGET_ALTIVEC"
"#"
"&& reload_completed"
....
Which then will be generated from rs6000_expand_vector_init. I can write this
if you want, it is just I cannot test this until Monday.
