This adds initial support for on-demand inputs by allowing new inputs to
be created with only a shared reference to the database. This allows
creating new inputs during a revision and therefore from inside tracked
functions.
392: Allow creation of tracked methods r=nikomatsakis a=Skepfyr
Fixes#319.
This allows users to annotate impl blocks with `#[salsa::tracked]` and
then create tracked methods by marking individual functions with
`#[salsa::tracked]`.
Note this requires your code that looks like:
```rust
#[salsa::tracked(jar = Jar)]
impl MyInput {
#[salsa::tracked]
fn tracked_fn(self, db: &dyn Db) -> u32 {
self.field(db) * 2
}
}
```
You get an error if you annotate a method with `#[salsa::tracked]` but forget to mark the impl block.
It got messier than I was hoping but I think it turned out alright, this would look really pretty if we had [inherent associated types](https://github.com/rust-lang/rust/issues/8995), but we don't. Annoyingly even if that landed I think we'd still need the attribute on the impl block just so that it was possible to create the associated struct somewhere as you can't put types inside an impl block (and they aren't accessible if placed inside a function).

This changes tracked methods from being annotated with `#[tracked]` to
`#[salsa::tracked]`. This improves consistency and allows outputting a
nicer error message if someone forgets to put the attribute on the impl
block.
376: add `synthetic_write` r=nikomatsakis a=XFFXFF
fixes#364
add `synthetic_write` and use it in test `lru_keeps_dependency_info`, the test will now be broken. We can use `lru_keeps_dependency_info` as a test for https://github.com/salsa-rs/salsa/issues/365, which already has a pr https://github.com/salsa-rs/salsa/pull/371.
379: Update test.yml r=nikomatsakis a=agluszak
- Add names to steps
- No need to run clippy AND check (https://stackoverflow.com/questions/57449356/is-cargo-clippy-a-superset-of-cargo-check)
- Run clippy on all targets with all features
- Fix issues reported by clippy
