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.

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

7fda874dd4 Blacklist some traits from being considered in where clauses
For Send/Sync/Sized, we don't handle auto traits correctly yet and because they
have a lot of impls, they can easily lead to slowdowns. In the case of
Fn/FnMut/FnOnce, we don't parse the special Fn notation correctly yet and don't
handle closures yet, so we are very unlikely to find an impl.

58b68966bf Handle resolution errors in where clauses
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.

787fb3e5ec Add HIR for where clauses & ignore impls with where clauses in trait resolution
This prevents any `impl<T> Trait for T where ...` from being treated as a
blanket impl while we don't handle where clauses yet.

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)

1076: Const body inference r=flodiebold a=Lapz

This is the second part of #887. I've added type inference on const bodies and introduced the DefWithBody containing Function, Const and Static. I want to add tests but im unsure on how I would go about testing that completions work.

40c6dd1f4c Merge #982
982: Implement BindingMode for pattern matching. r=flodiebold a=mjkillough

Implement `BindingMode` for pattern matching, so that types can be
correctly inferred using match ergonomics. The binding mode defaults to
`Move` (referred to as 'BindingMode::BindByValue` in rustc), and is
updated by automatic dereferencing of the value being matched.

Fixes #888.

c5ee60e05b Replace Display by a pretty printing trait for Ty
This allows removing the names from Adt and FnDef (and more later), as a first
step towards aligning more with chalk's Ty :)
