f59cd1a4a0 Merge #1515 
1515: Trait environment r=matklad a=flodiebold

This adds the environment, i.e. the set of `where` clauses in scope, when solving trait goals. That means that e.g. in
```rust
fn foo<T: SomeTrait>(t: T) {}
```
, we are able to complete methods of `SomeTrait` on the `t`. This affects the trait APIs quite a bit (since every method that needs to be able to solve for some trait needs to get this environment somehow), so I thought I'd do it rather sooner than later ;)

b1b12072ed Start handling environment in trait resolution 
I.e. if we are inside a function with some where clauses, we assume these where
clauses hold.

1834bae5b8 allow rustfmt to reorder imports 
This wasn't a right decision in the first place, the feature flag was
broken in the last rustfmt release, and syntax highlighting of imports
is more important anyway

4f8a49f43c Refactor method candidate generation a bit 
This fixes the order in which candidates are chosen a bit (not completely
though, as the ignored test demonstrates), and makes autoderef work with trait
methods. As a side effect, this also makes completion of trait methods work :)

a1ed53a4f1 More trait infrastructure 
- make it possible to get parent trait from method
 - add 'obligation' machinery for checking that a type implements a
   trait (and inferring facts about type variables from that)
 - handle type parameters of traits (to a certain degree)
 - improve the hacky implements check to cover enough cases to exercise the
   handling of traits with type parameters
 - basic canonicalization (will probably also be done by Chalk)

0242acae53 Turn ImplBlock into a copy type just containing IDs 
This makes it more like the other code model types.

Also make Module::definition_source/declaration_source return HirFileIds, to
make them more like the other source functions.
