This patch allows a machine description to specifiy a mode in a split
mattern, as in this example:
(define_split
[(set (match_operand:DI 0 "register_operand" "")
(match_operator:DI 1 "logical_op"
[(match_operand:DI 2 "register_operand" "")
(match_operand:DI 3 "arith_double_operand" "")]))]
"..."
[(set (match_dup 4) (match_op_dup:SI 1 [(match_dup 6) (match_dup 8)]))
(set (match_dup 5) (match_op_dup:SI 1 [(match_dup 7) (match_dup 9)]))]
"...")
Without the ":SI" the mode of the operation remains DImode and the
resulting pattern is not recognized.
