Introduce class adl_func_operation
This adds class adl_func_operation, which implements
argument-dependent lookup function calls.
Other function calls will be handled in a different way. However,
because ADL calls were created in a single spot in the C++ parser, and
because they had different semantics from the other cases, it was
convenient to treat them specially.
