New qual_name exporting logic in facebook-clang-plugins handles anonymous
classes in much better way. This allows us to simplify name generation for
classes that don't rely on a type of the object (which could be wrong for
methods from superclasses).

The static and global variables used in blocks don't appear in the ast as captured.
We need them however to try and find retain cycles involving those variables.
This diff adds a way of collecting the static variables used in blocks and treat them
like we treat other captured variables to find retain cycles.

When method was called from within other method,
the type of `this` parameter didn't have pointer in type.
This was due to wrong logic that stripped pointer out of the

We still need to strip the type when dereferencing reference variable.

Move dealing with init expressions from VarDecl_trans to standalone function.
This will be useful for constructor initializer.
I didn't improve anything, just moved stuff around so that no test breaks.
Main change is that we pass Sil code responsible for LHS (var dereference) as
result_trans.
Currently we assume that var_result_trans will have no nodes, no instructions,
no ids. This is true for current usages (it's always Sil.Lvar expression), but in the future it
will change.

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
