Now, one can use `let _p = ra_prof::cpu_profiler()` to capture profile
of a block of code.
This is not an out of the box experience, as that relies on gperfools

1432: Make fill_match_arm work with trivial arm r=matklad a=ironyman
Addresses this issue https://github.com/rust-analyzer/rust-analyzer/issues/1399
One minor issue I noticed is that complete_postfix creates an arm like this
```
match E::X {
<|>_ => {},
}
```
but fill_match_arms creates arms like this
```
E::X => (),
```

1439: Rich mapping of cargo watch output r=matklad a=etaoins
Currently we depend on the ASCII rendering string that `rustc` provides to populate Visual Studio Code's diagnostic. This has a number of shortcomings:
1. It's not a very good use of space in the error list
2. We can't jump to secondary spans (e.g. where a called function is defined)
3. We can't use Code Actions aka Quick Fix
This moves all of the low-level parsing and mapping to a `rust_diagnostics.ts`. This uses some heuristics to map Rust diagnostics to VsCode:
1. As before, the Rust diagnostic message and primary span is used for the root diagnostic. However, we now just use the message instead of the rendered version.
2. Every secondary span is converted to "related information". This shows as child in the error list and can be jumped to.
3. Every child diagnostic is categorised in to three buckets:
1. If they have no span they're treated as another line of the root messages
2. If they have replacement text they're treated as a Code Action
3. If they have a span but no replacement text they're treated as related information (same as secondary spans).

1436: Method resolution for slices r=sinkuu a=sinkuu
`impl<T> [T]` is separately defined in `core` and `alloc`, so I changed `def_crate` function in `method_resolution.rs` to return multiple crates.

The first cut was a bit rough with the blanket `unused_*` rule. This
trigger for things like `unused_mut` where the code is used but it's
suboptimal. It's misleading to grey out the code in those cases.
Instead, use an explicit list of things known to be dead code.

1434: Introduce cargo-watch.check-command option for Code extension r=matklad a=alekseysidorov
By this option you can replace `check` command in `cargo watch` by the something else like `clippy`.

1409: The Fall down of failures r=matklad a=mominul

Replaced all the uses of `failure` crate with `std::error::Error`.

Can be used like this:
```
$ cargo run --release -p ra_cli -- \
analysis-bench ../chalk/ \
--complete ../chalk/chalk-engine/src/logic.rs:94:0
loading: 225.970093ms
from scratch: 8.492373325s
no change: 445.265µs
trivial change: 95.631242ms
```
Or like this:
```
$ cargo run --release -p ra_cli -- \
analysis-bench ../chalk/ \
--highlight ../chalk/chalk-engine/src/logic.rs
loading: 209.873484ms
from scratch: 9.504916942s
no change: 7.731119ms
trivial change: 124.984039ms
```
"from scratch" includes initial analysis of the relevant bits of the
project
"no change" just asks the same question for the second time. It
measures overhead on assembling the answer outside of salsa.
"trivial change" doesn't do an actual salsa change, it just advances
the revision. This test how fast is salsa at validating things.
1408: Associated type basics & Deref support r=matklad a=flodiebold
This adds the necessary Chalk integration to handle associated types and uses it to implement support for `Deref` in the `*` operator and autoderef; so e.g. dot completions through an `Arc` work now.
It doesn't yet implement resolution of associated types in paths, though. Also, there's a big FIXME about handling variables in the solution we get from Chalk correctly.

1406: reuse AnalysisHost in batch analysis r=matklad a=matklad
We do some custom setup in `AnalysisHost`, like setting up LRU size. I figure it's a good idea to not duplicate this work in batch analysis, *if* we want to keep batch and non-batch close.
Long-term, I see a value in keeping batch a separate, lighter weight thing. However, because now we use batch to measure performance, keeping them closer makes more sense.
I'd also like to add ability to get completions by using batch analysis, and that will require ra_ide_api as well.
@flodiebold were there some reason why we haven't started with this approach from the start?

1407: Skip attrs in `ast::Literal::token` r=matklad a=sinkuu
`ast::Literal::token` panics on literals containing attributes. rust-analyzer crashed on the `rust-lang/rust` repository by parsing [a test containing this](9ebf47851a/src/test/run-pass/proc-macro/attr-stmt-expr.rs (L22-L25)).
