Summary:
When retrieving a value from a container, we previously had an arbitrary hack which would
- In java, give no ownership to the returned object (trying to be sound)
- In C++ give conditional ownership to the current method's first argument (trying to be complete, but doing it badly, as the first argument may not be the `this` object in a static method, or we might be accessing it through another parameter altogether).
Harmonise both by using the existing ownership of the container as ownership value for the returned object (leaning towards completeness).

Summary: C/C++ code can, in some cases, generate a large number of temporary (Sil) variables. Since we are already not reporting races on these, not recording them gives some perf back.

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.
