b42c5ced68 Implement BindingMode for pattern matching. 
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.

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.

we can simply pass the node.

897: Add basic const/static type inference r=flodiebold a=vipentti

This adds basic const/static type inference discussed in #887.

Currently the inference does not work for const/static declared inside a block. In addition the inference does not work inside the bodies of const/static.

6a04d1f292 Fix resolution of associated method calls across crates 
I think it'll be better to make the path resolution the number of unresolved
segments, not the first unresolved index; then this error could simply not have
happened. But I'll do that separately.

866: Implement basic support for Associated Methods r=flodiebold a=vipentti

This is my attempt at learning to understand how the type inference works by adding basic support for associated methods. Currently it does not resolve associated types or constants. 

The basic idea is that `Resolver::resolve_path` returns a new `PathResult` type, which has two variants, `FullyResolved` and `PartiallyResolved`, fully resolved matches the previous behavior, where as `PartiallyResolved` contains the `PerNs<Resolution` in addition to a `segment_index` which contains the index of the segment which we failed to resolve. This index can then be used to continue inference in `infer_path_expr` using the `Type` we managed to resolve.

This changes some of the previous apis, so looking for feedback and suggestions.

This should enable fixing #832

247d1c17b3 Change resolve_path to return the fully resolved path or PerNs::none 
This also adds new pub(crate) resolve_path_segments which returns the
PathResult, which may or may not be fully resolved. PathResult is also now
pub(crate) since it is an implementation detail.

816971ebc9 Implement basic support for Associated Methods and Constants 
This is done in `infer_path_expr`. When `Resolver::resolve_path` returns
`PartiallyResolved`, we use the returned `Resolution` together with the given
`segment_index` to check if we can find something matching the segment at
segment_index in the impls for that particular type.

701: Minor type inference tweaks r=flodiebold a=marcusklaas

Pass down expectation for reference expressions and type the guard in match expressions.

I wasn't able to add a test for the former addition because the type variable previously introduced would always resolve to the right type in the things I tried!

65864d85f9 Rename FnScopes -> ExprScopes 
The reason for this is that it describes scopes for any body expression, not
just that of a function. It did not actually refer to functions at all anymore.
