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 In this example we now get a dangling pointer dereference, so contains exactly doesn't work.

Summary: public This diff changes the way we treat enums in Infer.
1. The semantics of the translation is now correct, it was a bit incorrect before.
2. We don't add the enum types to the tenv anymore, which saves a lot of disk space
and avoids errors in the backend dealing with the enum type.

Summary:
The symbolic execution was not stopping in case an unitialized dangling pointer was
passed to a function and then dereferenced inside the callee.
What would happen is that a wrong footprint would be added to the unititialized pointer
at the end of the function call in the caller proposition.
This checks that if we do:
frame * new_footprint
checks that we do not add heap predicates to the frame into uninitialized local variables.
If we can identify the variable then we raise a danglind pointer dereference. If instead
we cannot give a good explanation we give an internal error.
The latter case should be temporary. We should find a general way to raise dangling pointer
deref instead of the internal error.
I also fixed the model of getc that was the way I found the problem.
Summary:
This adds a sentinel check every time a function carrying a sentinel attribute
is called, regardless of whether we have a definition for that function or not.
Summary:
@public
Sorting the fields in structs and classes. Was needed in the backend and forgotten.
Fixes the github issue https://github.com/facebook/infer/issues/90.
Test Plan: Added a new test that shows that we now get a spec for the example from the github issue.
