This is slightly hacky, but maybe more elegant than alternative solutions: We
just use a hardcoded Chalk trait ID which we special-case to have no impls.
1251: Chalk integration improvements r=matklad a=flodiebold
A few improvements that came up while working on where clause support:
- turn `implements` into a query again to improve performance
- allow skipping to a specific function with `analysis-stats`, e.g. `ra_cli analysis-stats --only world_symbols`
- deduplicate impls in impls_for_trait -- previously many impls e.g. from std where repeated many times, this should help performance as well...
- add a `HirDisplay` implementation for TraitRef (not used here anywhere, but useful for debugging)

1253: Share literal validation logic with compiler r=matklad a=matklad
This is neat: the unescape module is literary what compiler is using right now:
c6ac575648/src/libsyntax/parse/unescape.rs
So, yeah, code sharing via copy-paste!

1208: [WIP] Goto for Macro's r=matklad a=Lapz
Adds goto definition for macros. Currently only works for macros in the current crate ~~otherwise it panics~~. Proper macro resolution needs to be added for it to resolve macros in other crates.
Todo
- [X] Allow goto from macro calls
- [X] Fix panics
- [x] Add tests

1216: Basic Chalk integration r=matklad a=flodiebold
This replaces the ad-hoc `implements` check by Chalk. It doesn't yet any new functionality (e.g. where clauses aren't passed to Chalk yet). The tests that exist actually work, but it needs some refactoring, currently crashes when running analysis on the RA repo, and depends on rust-lang/chalk#216 which isn't merged yet 😄
The main work here is converting stuff back and forth and providing Chalk with the information it needs, and the canonicalization logic. Since canonicalization depends a lot on the inference table, I don't think we can currently reuse the logic from Chalk, so we need to implement it ourselves; it's not actually that complicated anyway ;) I realized that we need a `Ty::Bound` variant separate from `Ty::Param` -- these are two different things, and I think type parameters inside a function actually need to be represented in Chalk as `Placeholder` types.
~~Currently this crashes in the 'real' world because we don't yet do canonicalization when filtering method candidates. Proper canonicalization needs the inference table (to collapse different inference variables that have already been unified), but we need to be able to call the method candidate selection from the completion code... So I'm currently thinking how to best handle that 😄~~
