Detailed Description
ReturnStmt - This represents a return, optionally of an expression: return; return 4;
Note that GCC allows return with no argument in a function declared to return a value, and it allows returning a value in functions declared to return void. We explicitly model this in the AST, which means you can't depend on the return type of the function and the presence of an argument.

Retrieve the variable that might be used for the named return value optimization.
The optimization itself can only be performed if the variable is also marked as an NRVO object.
