Instrumenting the function entry post-inlining, without function exit, and with no parameters is exactly what we need. The `__cyg_profile_func_enter_bare` sounds good to me as a name. Thank you!

Unnecessary thoughts just to get a feeling we are on the same page: this could theoretically be made more orthogonal where `-finstrument-functions-after-inlining` could regulate whether the call is pre- or post-inlining, but I don't see how pre-inlining without parameters would be usable without too much DWARF digging, which is not too practical.
