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.

885: Parse token trees directy r=matklad a=matklad
This takes advantage of the recent macro refactoring to directly parse token stream into a syntax tree.

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
879: Fixes to goto definition r=vipentti a=vipentti
Previously goto definition would fail when the cursor was over the name of the definition. Now we should properly resolve to a `NavigationTarget` when on top of the name of a definition.
In addition this adds `name_range` field to `FileSymbol`, this further fixes goto_definition and symbol based navigation by allowing the `NavigationTarget` to actually have a `focus_range`, meaning instead of focusing on the start of the `full_range`, we can have the cursor focus on the name.
e.g. goto definition
```rust
fn bar() {
fn foo() { }
foo<|>();
}
```
Previously this would put the cursor at the start of the FN_DEF:
```rust
fn bar() {
<|>fn foo() { }
foo();
}
```
Now when using the symbol based resolving, we'll have a proper focus range and instead put the cursor at the start of the name.
```rust
fn bar() {
fn <|>foo() { }
foo();
}
```
This fixes#877 but doesn't contain the refactoring of the return type for `goto_definition`

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.
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.
