Creates a new query job

pub(super) fn await<'lcx>(     &self,     tcx: TyCtxt<'_, 'tcx, 'lcx>,     span: Span ) -> Result<(), CycleError<'tcx>>

Awaits for the query job to complete.

For single threaded rustc there's no concurrent jobs running, so if we are waiting for any query that means that there is a query cycle, thus this always running a cycle error.

Signals to waiters that the query is complete.

This does nothing for single threaded rustc, as there are no concurrent jobs which could be waiting on us
