Summary: More general version of the fix in D6138749. This diff moves RacerD's lock modeling into a separate module and uses the module in the HIL translation to check when a function has lock/unlock semantics.

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:
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.

Summary:
Record the list of access paths (if any) used in the index expression for each array access.
This will make it possible to use array accesses as sinks in Quandary

Summary:
Conversion and reformat of infer source using ocamlformat
auto-formatting tool.
Current status:
- Because Reason does not handle docstrings, the output of the
conversion is not 'Warning 50'-clean, meaning that there are
docstrings with ambiguous placement. I'll need to manually fix
them just before landing.
