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

(WIP)
Follow the instructions from https://github.com/salsa-rs/salsa/issues/340#issuecomment-1210153085.
Still not sure what to do with `fmt_index`...

360: Permit renaming constructors, getters and setters r=nikomatsakis a=MihailMihov
The goal is to add an option `constructor_name` to `#[salsa::input]`, `#[salsa::interned]` and `#[salsa::tracked]` that allows changing the name of the generated constructor. After that add attributes `get` and `set` to the fields which allow overriding the names of the getters and setters. In the end the following snippet should compile and work:
```rust
#[salsa::interned(constructor = from_string)]
struct MyInterned {
#[get(text)] #[set(set_text)] #[return_ref]
field: String,
}
impl MyInterned {
pub fn new(db: &dyn Db, s: impl Display) -> MyInterned {
MyInterned::from_string(db, s.to_string())
}
pub fn field(self, db: &dyn Db) -> &str {
self.text(db)
}
pub fn set_field(self, db: &mut dyn Db, id: String) {
self.set_text(&mut db, id)
}
}
```

352: Add options to tracked funcitons for lru capacity r=nikomatsakis a=XFFXFF
fixes#344
Now we can write something like the following to set the lru capacity of tracked functions
```rust
#[salsa::tracked(lru=32)]
fn my_tracked_fn(db: &dyn crate::Db, ...) { }
```
some details:
* lru should not be combined with specify. We will report an error if people do #[salsa::tracked(lru = 32, specify)]
* set 0 as default capacity to disable LRU (Because I think doing this would make the code simpler when implementing `create_ingredients` of tracked functions).
* old salsa support to change lru capacity at runtime, [as noted here](https://salsa-rs.github.io/salsa/rfcs/RFC0004-LRU.html?highlight=change#reference-guide), but we do not support this now
