The patches looks good. It doesn't look like we're adding sampling to any performance critical code. I can r+ the cocoa changes but maybe we need someone else to review a patch that touch other modules. They just need to 'ok' adding a few cycles to these functions.

We should just pick a single standard and use it everywhere for all 3 patches. I think I would vote for that to be:
SAMPLE_LABEL_FN

The info parameter here isn't needed.

Do you think PRETTY_FUNCTION is to verbose? Maybe using __func__ is enough. To be honest I think PRETTY_FUNCTION is too verbose because it include parameters and return type, and that __func__ is ambiguous because it doesn't include namespace.

This also gets rid of the function macros because they don't provide what we want.

The naming is still pretty adhoc throughout as I'm not really sure what a good convention should be. I think we can figure that out as we add more labels and use them more.

Please comment in bugs when they land on inbound, especially if they've been backed out and/or re-landed.  It takes some of the pain out of merging.
