[PATCH] D87737: Add -fprofile-update={atomic,prefer-atomic,single}

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

I think an interesting extension (not in GCC) is `-fprofile-update=set`, a boolean counter like `-covermode set` in go: sometimes we don't need the numbers at all.
