Summary:
- do a semantic analysis of each variable initializer to figure out if they need initialization
- add a flag to globals that is true when they are `constexpr`. In that case, no analysis is needed as the user + compile guarantee that it is a compile-time constant.

Summary:
Right now, taint gets lost if it flows into a constructor or procedure whose implementation is missing.
Since the core Java (e.g., String) and Android classes (e.g, Intent) are among these, this is bad.
We could handle this by writing a bunch of models instead, but that would be a lot of work (plus we may still miss cases).

In several places the tests were using whatever 'infer' executable was

This also adds `-a compile` support to `InferClang`. This is needed for the
`xcodebuild` integration, which is hard to fold into the same binary as the
rest.

1. Collect all globals (transitively) accessed in any given procedure.
2. Once the interprocedural analysis has finished, look at globals accessed in
initializers that do not belong to the current translation unit.

Summary:
Create dummy functions representing the initializers of global variables. This
is so we can implement checks in the backend that can look at the initializer
expressions of global variables. We try not to create these dummy functions
when the initializer is not present, although for some reason we sometimes end
up with empty initializers.
Also add source file info to global variables in the backend (Pvar.re).

Before, if I wrote code like
```
x = src()
sink(x)
sink(x)
```
we would report three times instead of two.
The first flow would be double-reported.

Summary:
This changes executions of the former InferClang into a function call. In
particular, it can be called several times per execution.
The new InferClang must be called as if it was clang, and knows how to run
clang with our plugin to get the AST of the source file.

This changes the algorithm for pure join to keep the constraints that,
after normalization, occur in both arguments. Previously pure join

We were previously leaking the passthroughs of the callee into the caller.
We definitely don't want to do this since it could make the summaries higher up in the call stack explode.
If we need to know the passthroughs of a callee, we can always read them from the callee's summary.
