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.

065d398701 Add trait obligations for where clauses when calling functions/methods 
E.g. if we call `foo<T: Into<u32>>(x)`, that adds an obligation that `x:
Into<u32>`, etc.

1491: More clippy r=matklad a=kjeremy

A few more clippy changes.

I'm a little unsure of the second commit. It's the trivially_copy_pass_by_ref lint and there are a number of places in the code we could use it if it makes sense.

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

b8cae2cf8f check for cancellation when executing queries 
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.

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)
