[Bug target/31478] New: Typo in sse2_umulv2siv2di3 pattern

There are
(define_insn "sse2_umulv2siv2di3"
[(set (match_operand:V2DI 0 "register_operand" "=x")
(mult:V2DI
(zero_extend:V2DI
(vec_select:V2SI
(match_operand:V4SI 1 "nonimmediate_operand" "%0")
(parallel [(const_int 0) (const_int 2)])))
(zero_extend:V2DI
(vec_select:V2SI
(match_operand:V4SI 2 "nonimmediate_operand" "xm")
(parallel [(const_int 0) (const_int 2)])))))]
"TARGET_SSE2 && ix86_binary_operator_ok (MULT, V8HImode, operands)"
"pmuludq\t{%2, %0|%0, %2}"
[(set_attr "type" "sseimul")
(set_attr "mode" "TI")])
I have 2 questions:
1. Is ix86_binary_operator_ok needed here?
2. If yes, why is V8HImode used?
