genmatch.c (dt_node::gen_kids_1): If generic_exprs include SSA_NAME and exprs_len || fns_len...

	* genmatch.c (dt_node::gen_kids_1): If generic_exprs include SSA_NAME
	and exprs_len || fns_len, emit the code for SSA_NAME next to the exprs
	and fns handling, rather than in a separate case SSA_NAME.
