9c7ac995d8 Make salsa buildable on power 
rust-analyzer fails in rust-lang/rust repo on the power target,
because it doesn't have `AtomicU64`. So, lets just use `AtomicUsize`
as a revision number.

Semantically this is wrong, as we are not using revision to address
arrays, but, practically, it's a nice compromise to build on targets
without AtomicU64 and to have large revision numbers on most relevant
targets.

a6b162aba1 Replace mpsc channels with hand-written future implementation 
cargo llvm-lines shows that some amount of llvm lines is spend on
`std::mpsc`. Given that this is not the most loved standard library
module, and that our usage of mpsc is extremely limited, it seems
worth-while to implement oneshot channel using parking_lot.

380306930b feat: Prune unnecessary dependencies 
Only AtomicCell is used from crossbeam and SmallRng from rand so we can
easily disable the default features

0a94efeac3 emit WillChangeInputValue before new revision (breaking change!) 
Otherwise we need to borrow the `db` in `with_incremented_revision`
and it's a pain.

8c133e7a4d make synthetic_write require &mut self (breaking change!) 
This was an oversight before -- the current type implies that
one introduce a synthetic write (and hence a new revision) from
a `Frozen<DB>`! Not cool.

0e01067d55 feat: Allow queries to avoid panics on cycles 
Quickest POC I could create to get some potentially cyclic queries to
not panic and instead return a result I could act on. (gluon's module
importing need to error on cycles).

```
// Causes `db.query()` to actually return `Result<V, CycleError>`
fn query(&self, key: K, key2: K2) -> V;
```

A proper implementation of this would likely return
`Result<V, CycleError<(K, K2)>>` or maybe larger changes are needed.

not the best fit semantically
