[PATCH] D69384: Add unlikely attribute to outlined function

[Vedant Kumar via Phabricator via llvm-commits]

vsk added a comment.

Yes, this does need a test, but I'm also not sure why this belongs in the hot/cold splitting pass.

It's possible to mark functions with the `cold` attribute outside of the splitting pass. Shouldn't all of these cold functions should have a `.unlikely` section prefix? If so, setting the section prefix should be done later (say, in PreISelLowering).
