[PATCH] D28404: IRGen: Add optnone attribute on function during O0

[Paul Robinson via Phabricator via cfe-commits]

probinson added a comment.

Maybe instead, pass a flag to enable setting optnone on everything when the driver sees `-O0 -flto`?  The patch as-is obviously has a massive testing cost, and it's easy to imagine people being tripped up by this in the future.
