Summary:
public
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.
