Auto merge of #27191 - pnkfelix:sidestep-unary-negate-warning, r=alexcrichton

Browse Source 
Work around unary negation to-be-feature-gated warning by replacing references to `-1` as a `ast::NodeId` with `ast::DUMMY_NODE_ID`, which seems like a better notation to use (it is currently also `-1`.

(AFAICT the code is not *relying* on the value `-1` anywhere, it really just needed a dummy value for when the input is `None`.)
