Summary: Gflags is a popular library used to create command line arguments. Flags shouldn't flow directly to `exec` etc.

Summary: In particular, the heuristics for propagating taint via unknown code needs to be aware of the frontend's trick of introducing dummy return variables.

Summary:
There are two pointer-related operations you can do in C++ but not Java that we need to support in taint analysis:
(1) `*formal_ptr = ...` when `formal_ptr` is a formal that's a pointer type. Java doesn't have raw pointers, so we didn't need to handle this case.
(2) Passing by reference, which Java also doesn't have (everything is pass-by-value).

Summary:
Needed because this is how the Clang frontend translates returns of non-POD, non pointer values (I think)?
Will handle the more general case of pass by reference soon.

Summary:
Run all clang tests with project-root at `infer/tests`. I need it because we'll start resolving symbolic links
soon and some tests would lead outside of project root which means we'd start seeing absolute paths in recorded tests.

When loading results from a json file, sort them. This prints results in some
sane order for both --issues-test and --issues-txt, removing the need for
post-processing of the result.

Summary: A must-have for reporting taint errors and any other interprocedural error where the trace is sufficiently complex.

fbshipit-source-id: 26b3b2b
Summary:
Previously, we recorded direct sinks as sinks and transitive sinks as passthroughs. This makes it difficult to create an expanded interprocedural trace when recording an error because we can't distinguish between sinks (which we want to expand) and passthroughs (which we don't). This diff changes recording of sinks so that a sink is now the *last* function in a trace to call a sink. To find out what the original sink was, the summary for the transitive sink in the trace will now need to be (recursively) expanded until we bottom out in the original sink.
Will do the same for sources in a follow-up diff.

Summary:
Needed to support upcoming diff(s) that change the nature of sources/sinks in a trace. Today they are the *original* source/sink, but in the future they will be the *transitive* source/sink (last procedure to return a source/call a sink).
This new convention will make the `returnAllSources`/`callAllSinks` form of these tests not so useful, since `returnAllSources`/`callAllSinks` will now show up as a single source/sink in the trace (at least without expanding the trace). By making these tests intraprocedural, we can make sure that we're still testing everything that we want to.
