Had it been only 1 hole per side, I would have kept them, and chanced it. But two, and opposing each other vertically, means it has two sources for a crack to propagate.
I'd toss the bar.
But if you insist on using it, then try to reinforce that spot. Try wrapping it with fiberglass and resin. It'll give you a fighting chance when the bar snaps. Since it's wrapped, you won't see the fiberglass and resin.
