Add optional field to trans_state that denotes variable that is being initialized.
This information will be used by certain constructs (such as c++ constructors or
list initialization).
Passing it in trans_state will enable us to deal with more complicated AST structures where
there might be multiple nodes between variable declaration and its initialization.

It is currently happening intermittently which makes it hard to debug.
Other inconsistencies don't cause the whole analysis to crash normally,

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).

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.
