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.

Summary:
The clang frontend has bugs. When a bug we know about happens some
exception is raised and, most of the time, logged away so as not to
crash the whole process. This catching of exceptions wasn't done from
testDeterminator so it could crash where capture didn't. This diff wraps
the crashy function in test determinator to avoid that.

Summary:
Use `ignore` instead, as this will warn if the argument is an arrow type,
unlike `let _ = ...`. This makes the code more future-proof: if an argument is
added to a function called in `let _ = f x` then the compiler will complain
instead of silently turning a value into a partial evaluation.
Also got rid of particularly irksome `let _ = <stuff returning unit> in` where I could.

Summary:
The internal concept of "kind" should in fact be named "severity" to match the convention used by many other tools, whereas the internal concept of "severity", i.e "HIGH", "MEDIUM" and "LOW" was never used and in any case redundant with the concept of "info", "warning", "error".
This diff maps both the "kind" and "severity" fields to value of the form "advice", "info", "warning", and "error" to be able to progressively migrate the code using the "kind" field.

Summary:
One source of non-determinism is racing on procedure summaries when reporting. In particular, the summary of a method may be computed and stored by one thread, but another may be trying to report on it (eg, in cluster checkers).
One solution (at least until everything is in sqlite) is to have separate files just for the reports, a la linters. This diff improves the interface of LintIssues and generalises it ahead of using it in other analysers.

Summary:
Naming a variable `_foo` makes the compiler not warn about them if they are
unused, but there are lots of instances of such variables in the code where
they are in fact used, defeating the warning and introducing confusion for
those used to this naming convention.
Basically `sed -i -e "s/ _\([a-zA-Z][a-zA-Z0-9_']*\)/ \1_/g" **/*.ml` followed
by manual fixing of compilation errors (lots of `compare__foo` ->
`compare_foo_`).

Summary:
The clang frontend uses `assert false` for unimplemented features that should
abort method translations, as well as for genuine internal errors.
Distinguishing between the two, we can fail hard on the latter and not the
former.
1. This introduces a new exception `Unimplemented` that is used instead of `assert false` where appropriate.
2. Changed some other cases into `die ...` (when there's an error message to display)
3. Wherever a path in the code that we assumed to be unreachable was observed reachable, we now raise `IncorrectAssumption`. These should be fixed, but the fixes are not obvious.
