I personally find it kind of baffling to have the same tree code act
differently in GENERIC and GIMPLE, a la SWITCH_EXPR.  It seems to add
confusion for minimal benefit.  If you are suggesting that the single
tree code GOMP_PARALLEL have different operands in GENERIC and GIMPLE,
can I suggest that you instead use two different tree coes?
