Paul Fultz II a90caa7e5a Fix issue 9006: False positive: Return value of function std::move() is not used. 
This is trying to fix the issue by fixing the ast and symbol database. First, the ast nodes will be created for the init list and the symbol database will not mark it as a scope. I am not sure if this is the correct approach as I dont really understand how the AST part works.

It did change the AST for `try {} catch (...) {}` but that is because it incorrectly treats `try {}` as an initializer list.
