Summary:
public This assert false causes the whole analysis to crash.
It is currently happening intermittently which makes it hard to debug.
Other inconsistencies don't cause the whole analysis to crash normally,
so this one seems to be too strict.

Use Infer traces to follow the chain of calls from methods annotated PerformanceCritical to the methods annotated as Expensive.
This contains direct jumps from method definition to method definition. So the traces are of the form:
method definition of m1 -> definition of m2 -> definition of m3 -> ... -> definition of mN annotated as Expensive
In the next diff, I will make the checker create traces of the form:
definition of m1 -> call to m2 -> definition of m2 -> call to m3 -> ... -> call to mN -> definition of mN annotated as Expensive
and then simplify the error message whenever the chain of call is longer than, say, 5 calls.

Reuse logic in cFrontend.ml to deal with nested structs. This allows to have less duplicated logic which will result
in less bugs.
As a bonus, it fixes the problem of nested template class (which wasn't be handled right).
And one random fix in c_type -> sil_type conversion (I'm amazed it worked before)

In the case of Java, the name of the method is enough to lookup the summary of the callees and run the symbolic execution. This revision separates the case of method call in Java and in C, C++ and Objective C. Most of the code for executing method calls was Clang specific and this is an intermediate step to be able to run the capture and analysis on demand.

This diff cleans up the detection of assertion failures in C, C++ and Objective C which was previously hacked on top of the tracing mode for Java. The code is also generalized to detect any custom errors which can be defined using the `__infer_fail` builtin, and the case of assertion failure is now just the specific case of translating `assert` using `__infer_fail` directly in the clang frontend.

Summary: public Crashes during the analysis are classified as timeouts in the .specs file. In addition, when there is a timeout, it does not say *why* the timeout occurred (hard time, symops, or recursion). This diff adds this information to the .specs file and adds a "fail hard" mode where crashes and timeouts will actually stop the analysis in developer mode (but will still be hidden in the normal production mode).
