Add extra dereference when accessing fields that have T& type. It is similar
to what is done when accessing variables of T& type.
The only difference is that we need to handle constructor initializer list
separately (this is the only place where the field can be initialized)

I have seen enough comments in this space by people during code review to switch on the analyses the compiler can already do. This diff is an automated renaming of unused identifiers to _, with a few additional changes made when reading the diff of the results for things that stood out as particularly strange. This base-lines all of the existing warnings. I'm not sure this is a good idea, since it might be better for those familiar with each part of the code to look at these warnings and use them as pointers to suspicious code.

This expression is used to value-initialize non-class types. Per definition of value initialization for non-class types:
1. If it's an array, value-initialize each of its elements
2. Otherwise, zero-initialize it

xvalues is concept introduced in C++11. While they are not same as lvalues, they have one common trait:
They have identity which means that:
> it's possible to determine whether the expression refers to the same entity as another expression, such as by comparing addresses of the objects or the functions they identify (obtained directly or indirectly);
It means that as far as backend is concerned, they should be treated in same way. Right now there is no concept of "move" in the backend and so we don't have
to differentiate between them.

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.
