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:
Do not use the deprecated (and slower) `#infer` flavor. Instead, `infer-run`
runs capture with the `#infer-capture-all` flavor, followed by merging targets,
followed by the analysis.
Move the call to `MergeCapture` around to make this change easier.

Summary:
With current model, there are issues with cxx range loop. It looks like
it comes from std::vector::size model.
example of such FP:
```
int t = vec.size();
for(auto& elem : vec) {
auto x = elem
}
```

Summary:
It's nice to have "raw" as the default kind of access path, since it's used much more often than the abstraction.
This is also a prereq for supporting index expressions in access paths, since we'll need mutual recursion between accesses and access paths.

This is unsound but will help the analysis to report less false alarms with the common pattern:
if (a.get() != null) {
a.get().foo();

Previously, only the bug type + file name (up to renaming) were taken into
account, which was too coarse. The key is file-independent and provides
additional signal.

Cosmetic changes to the output of `make clean` and `make test-replace`.
Run the inferTraceBugs tests from tests/build_systems/ like other such e2e

Works the same way as read/write races on fields, except that are more relaxed (er, unsound) in deciding whether two containers may alias.
This is needed to avoid reporting a ton of FP's; full explanation in comments.
