Great, if possible Sean or David could you commit this for me? I don't have
commit access.

As for your question. Sean and I have actually experienced warnings
resulting from a difference in inlining choices in different TU's but we
will definitely be bringing this up very soon as a separate discussion.
These flags were mostly to deal with `instrprof_error::unknown_function`
which for our use case tends to be pretty spammy but not very helpful.
