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
use them for `buck targets`. It's hard to know which options to take into
account for which Buck subcommand, so just filter out known-incompatible ones.

Buck reads the version on stderr or, very recently, from either stdout or stderr.
This makes infer output the version of stderr when called from Buck or invoked as javac, and on stdout otherwise.

Summary:
Whenever we see a use of a lock, infer that the current method can run in a multithreaded context. But only report when there's a write under a lock that can be read or written without synchronization elsewhere.
For now, we only infer this based on the direct usage of a lock; we don't assume a caller runs in a multithreaded context just because its (transitive) callee can.
We can work on that trickier case later, and we can work on smarter inference that takes reads under sync into account. But for now, warning on unprotected writes of reads that occur under sync appears to be too noisy.

Summary:
This will allow most of the checkers, except the bi-abduction, to skip the analysis on the specialized clone of the methods used to handle dynamic dispatch. Doing this, we can run the bi-abduction analysis using:
infer -a checkers --biabduction
without risk of conflicts on the resolution of dynamic dispatch.

Summary:
It looks like the old code for expanding access paths assumed that `FormalMap.get_formals_indexes` assumed the returned list tuples would be sorted by index, but it's actually sorted by var name.
As a consequence, formals might be expanded into the wrong actuals.
This diff fixes the problem by not relying on `get_formals_indexes`.
