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

1409: The Fall down of failures r=matklad a=mominul
😁
Replaced all the uses of `failure` crate with `std::error::Error`.
Closes#1400
Depends on rust-analyzer/teraron#1

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.

1068: profiling crate first draft r=matklad a=pasa
I've made this first draft for #961
Could you look at it? Is this something what you are looking for?
It has lack of tests. I can't figure out how to test stderr output in rust right now. Do you have some clues?
Additionally I'm thinking about to implement procedural macros to annotate methods with this profiler. Will it be helpful?

1021: Wasm dependencies r=matklad a=detrumi
As a first step towards running RA on WASM (see #1007), this tweaks the dependencies somewhat so that projects built using `wasm-pack` can use `ra_ide_api` as a dependency.
There were two problems:
- use of undeclared type or module `MmapInner`
This error occurred because of the `memmap` crate, as a dependency of `fst`
Solution: specify `default-features = false` for the `fst` package (see https://github.com/BurntSushi/fst/issues/70)
- use of undeclared type or module `imp`
This happened in the `wait-timeout` crate ([which uses `Command` under the hood](https://github.com/alexcrichton/wait-timeout/issues/18)), a dependency of `rusty-fork` which is a dependency of `proptest`.
Solution: move `proptest` to dev-dependencies and add `#[cfg(test)]` to the `test_utils` crate.
**Edit:** Oh, that causes trouble with resolving the import when running the tests. Hmm...

997: Improve filtering of file roots r=matklad a=vipentti
`ProjectWorkspace::to_roots` now returns a new `ProjectRoot` which contains
information regarding whether or not the given path is part of the current
workspace or an external dependency. This information can then be used in
`ra_batch` and `ra_lsp_server` to implement more advanced filtering. This allows
us to filter some unnecessary folders from external dependencies such as tests,
examples and benches.
Relates to discussion in #869

The new rowan uses arena allocator for red nodes which helps
slightly (5% on std completion test) with performance but should help
quite a bit with avoiding memory fragmentation.
358: Add support for formatting entire document with rustfmt r=matklad a=aleksanb
Attempting to format a document when rustfmt isn't installed will result
in an error being returned to the frontend. An alternative
implementation would be returning zero replacements.
Part of https://github.com/rust-analyzer/rust-analyzer/issues/160.

This will really become necessary when we implement generics, but even now, it
allows us to reason 'backwards' to infer types of expressions that we didn't
understand for some reason.
We use ena, the union-find implementation extracted from rustc, to keep track of
type variables.
