[CFG] [analyzer] Don't add construction context to a return-by-reference call.

Call expressions that return objects by an lvalue reference or an rvalue
reference have a value type in the AST but wear an auxiliary flag of being an
lvalue or an xvalue respectively.

Use the helper method for obtaining the actual return type of the function.

Fixes a crash.
