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)).

1404: Fight down failures! r=matklad a=mominul
issue #1400
Now only `ra_tools` crate depends on `failure`, should I also fight those? 😁

The issue was windows specific -- cancellation caused collection of
bracktraces at some point, and that was slow on windows.
The proper fix here is to make sure that we don't collect bracktraces
unnecessary (which we currently do due to failure), but, as a
temporary fix, let's just not force their collection in the first
place!
Note that we can't just remove CheckCanceled trait altogether:
sometimes it's useful to check for cancellation while the query is
running! We do this, for example, in the name resolution fixed-point
loop.
1396: fixed wrong links again r=matklad a=zbelial
Hi
Sorry about that I didn't check all links in my previous PR and two of them were incorrectly fixed.
I think they are all proporly fixed this time :)

1394: Fix hover for pat that shadows items r=matklad a=sinkuu
```rust
fn x() {}
fn y() {
let x = 0i32;
x; // hover on `x` is expected to be `i32`, but the actual result was `fn x()`
}
```
This was because: if [`res.is_empty()`](656a0fa9f9/crates/ra_ide_api/src/hover.rs (L205)), it fallbacks to "index based approach" and adds `fn x()` to `res`, which makes [`res.extend(type_of)` below](656a0fa9f9/crates/ra_ide_api/src/hover.rs (L260-L266)) not happen.
