Summary:
Due to limitations in our Buck integration, the thread-safety analysis cannot create a trace that bottoms out in a Buck target that is not a direct dependency of the current target.
These truncated traces are confusing and tough to act on.
Until we can address these limitations, let's avoid reporting on truncated traces.

Summary:
Relative paths in jbuilder + `S **` seem to be a losing combo. Spell out the directories instead.
This was obtained via letting jbuilder generate .merlin, then curating it by hand.

Summary:
:
Make both buck capture and compilation database handle buck command line arguments and invoke buck query the same way.
Plus allow:
- target patterns `//some/dir:` and `//some/dir/...`. However since `//some/dir:#flavor` and `//some/dir/...#flavor` are not supported, they need to be expanded before adding the infer flavor.
- target aliases (defined in `.buckconfig`)
- shortcuts `//some/dir` rewritten to `//some/dir:dir`
- relative path `some/dir:name` rewritten to `//some/dir:name`

Summary:
If you write
```
boolean readUnderLockOk() {
synchronized (mLock) {
return mField;
}
}
```
it will be turned into
```
lock()
irvar0 = mField
unlock()
return irvar0
```
in the bytecode. Since HIL eliminates reads/writes to temporaries, it will make the above code appear to perform a read of `mField` outside of the lock.
This diff fixes the problem by forcing HIL to perform all pending reads/writes before you exit a critical section.

Summary:
Linters are now considered a "checker", like backend checkers. This makes, eg,
`--racerd-only` disable the linters, which is more intuitive.
We can now express `-a linters` and `--clang-frontend-action` in terms of these
two new options. For instance, `-a linters --clang-frontend-action lint` is the
same as `--linters-only --no-capture`.
This is another step in the direction of getting rid of `--analyzers`.

Summary:
Before this change, analyses using HIL needed to pass `IdAcessPathMapDomain.empty` to abstract interpreter, and would get back the map as part of the post.
This is a confusing API and was a pain point for Dino in trying to use HIL.
This diff adds a HIL wrapper around the abstract interpreter that hides these details.
It replaces `LowerHIL.makeDefault` as the new "simplest possible way" to use HIL.

The options passed via `--Xbuck` are usually meant for `buck build` but we also
