63e1e63a91 start cleaning up the resolution
Nameres related types, like `PerNs<Resolution>`, can represent
unreasonable situations, like a local in a type namespace. We should
clean this up, by requiring that call-site specifies the kind of
resolution it expects.

b8c1e402fa Make type walking infrastructure a bit nicer
If/when we switch to using Chalk's Ty, we'll need to replace this by its `Fold`
trait, but I didn't want to import the whole thing just yet.

16a7d8cc85 Add impl Trait and dyn Trait types
- refactor bounds handling in the AST a bit
 - add HIR for bounds
 - add `Ty::Dyn` and `Ty::Opaque` variants and lower `dyn Trait` / `impl Trait`
   syntax to them

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.

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

a4eb1a546c Differentiate Tuple / FnPtr type constructors by cardinality
This is necessary because Chalk (reasonably) expects each 'struct' to know how
many type parameters it takes.

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)

7faae12311 Remove FnSig from FnDef type
It doesn't need to be in there since it's just information from the def. Another
step towards aligning Ty with Chalk's representation.

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 :)

dcfb4ee702 Split ty.rs into several modules
It was just getting too big. We now have:

 - ty: the `Ty` enum and helpers
 - ty::infer: actual type inference
 - ty::lower: lowering from HIR to `Ty`
 - ty::op: helpers for binary operations, currently
