This commit avoids precision loss on pruning.
// x -> [s$1, s$2]
if(x) { ... }
// x -> ?
before: x -> [min(0, s$1), max(0, s$2)]
because two x values, [0, 0] (true case) and [s$1, s$2] (false case), were joined after the if branch.
after: x -> [s$1, s$2]

Summary:
Infer is only using clang's AST which means it can ignore flags passed to LLVM backend via `-mllvm` flag.
It will make it easier to maintain compatibility between different versions of clang/LLVM (ie. when flag is not available in LLVM used by infer)

Summary:
This just makes the warnings silent for now. We may improve the analysis to check if the null check on the captured fields are consistent with the annotation on the corresponding parameters.
Eradicate also has the same issue. I added a test to outline this. The biabduction analysis will also probably fail on the same of annotation lookup. We may want implement the proper fix at the level of `Annotation.field_has_annot`.

Summary:
Fixes 2 issues with the build:
- The OCaml dependencies (Version.ml, atdgen-generated stuff, ...) would be generated twice when running `make -j test` from a clean tree, because `make` has no inter-Makefile visibility over common dependencies.
- We would run `atdgen` twice: once for the .ml, once for the .mli, even though one invocation is enough for both.
Add `make ocaml_clean` to nuke only the OCaml code (in particular because
rebuilding the C++ code in the plugin is slow when all I want to get rid of the
OCaml stuff).

Summary:
First steps towards implementing diff analysis functionalities inside infer
itself. What works: run infer, checkout parent, re-run infer, checkout top
revision, compute the reportdiff (but no final surfacing on the console). Lots
of TODO still, inlined in the code.

Summary:
Allowing the user to configure where to store the JSON report is asking for
trouble. In fact, some places in the code hardcoded "results.json" anyway.
Someone wanting to have results.json somewhere else can still copy report.json
once infer has run.

This reverts commit 7177bb6b8af1404fde408ead4750ef48ed9bdaff.
In practice, `extract_filepath` exhausts the call stack, leading to "RuntimeError: maximum recursion depth exceeded" exceptions. Perhaps a loop needs to be used instead.

Summary:
Problem: The analyzer did not know that the value of `v.size()` is an alias of `v.infer_size`, so `v.infer_size` is not pruned by the if condition. As a result it raises a false alarm.
void safe_access(std::vector<int> v) {
if (v.size() >= 10) {
v[9] = 1; // error: BUFFER_OVERRUN Offset: [9, 9] Size: [5, 5]
}
}
void call_safe_access_Good() {
std::vector<int> v(5, 0);
safe_access(v);
}
Solution: Adding alias for return value to the abstract domain.
Now Inferbo can prune `v.infer_size` because it knows that the value of `v.size()` is an alias of `v.infer_size`. There is already an alias domain in Inferbo, so we added a specific room for the retrun value.

1. Allow it to forward -version calls to javac (so that if the build system wants
to check the compiler version it doesn't end up with Infer's version)
2. Preserve empty arguments:

Current status:
- Because Reason does not handle docstrings, the output of the
