Summary:
Warning: This might be a bit brutal.
PerfStats and EventLogger are pretty much subsumed by `ScubaLogging`.
It seems no one has been looking at the data they generate recently.
Let's delete them! If we need to re-implement some parts later on, let's
do that using `ScubaLogging`, which is better (eg, still produces data
when infer crashes).
Things we lose:
- errors in the clang frontend due to missing decl translation, etc.
- errors in biabduction due to timeouts, functions not found, etc.
We could also re-implement these using BackendStats and ScubaLogging
instead of brutally deleting everything.
