[PATCH] Handle captured statements for predefined expressions

[Erik Olofsson]

  I think this commit broke lambdas inside templated functions where codegen asserts:
    template <typename Type>
    bool Func(Type Value) {
      auto Function = []() {
        return __FUNCTION__;
      };
      return Function();
    }

    int main() {
      return Func(1);
    }

  -

    (cast<ConstantArrayType>(E->getType())->getSize() - 1 == FunctionName.size() && "Computed __func__ length differs from type!")
