This contains the syntax range of the name itself, allowing NavigationTarget to
properly set the focus_range. This should make it so that when using symbol
based navigation, we should always focus on the name, instead of the full range.
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

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.
864: Fix handling of generics in tuple variants and refactor a bit r=matklad a=flodiebold
(The problem was that we created separate substitutions for the return value, so we lost the connection between the type arguments in the constructor call and the type arguments of the result.)
Also make them display a tiny bit nicer.
Fixes#860.

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.
844: Refactor find_all_refs to return ReferenceSearchResult r=vipentti a=vipentti
This refactors `find_all_refs` to return a new `ReferenceSearchResult` based on feedback in #839.
There are few questions/notes regarding the refactor:
1. Introducing `NavigationTarget::from_bind_pat` this simply forwards the call to `NavigationTarget::from_named`, could we just expose `from_named` directly as `pub(crate)` ?
2. Added an utility method `NavigationTarget::range` since there were few places where you would use `self.focus_range.unwrap_or(self.full_range)`
3. Implementing `IntoIterator` for `ReferenceSearchResult`. This turns `ReferenceSearchResult` into an iterator over `FileRanges` and allows previous code to mostly stay as it was based on the order that `find_all_refs` previously had (declaration first and then the references). I'm not sure if there is a way of doing the conversion to `IntoIter` without the allocation of a new vector
4. Is it possible to have a binding without a name? I'm not sure if the `NavigationTarget::from_bind_pat` can cause some edge-cases that previously were ok
This fixes#835.

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.
