1293: Pass `--all-targets` to `cargo watch` r=matklad a=aleksijuvani
A trivial change, but passes the `--all-targets` flag to `cargo watch`. This enables inline diagnostics for the example, bin and test targets. Previously, modifying an example would trigger a change notification for `cargo watch`, but `cargo check` does not actually check these unless either `--all-targets` or `--examples` is specified.

1286: Add infer for generic default type r=flodiebold a=edwin0cheng
This PR add infer support for generic default type:
```
struct Gen<T=u32> {
val: T
}
```
* add the (unresolved) defaults from the definition to GenericParams
* add a query generic_defaults that resolves those defaults to types and returns a Substs
* add the missing type in `substs_from_path_segment`
* add tests
based on the idea in this [comment](https://github.com/rust-analyzer/rust-analyzer/issues/1099#issuecomment-484206279)

1267: Macro expand to r=edwin0cheng a=matklad
closes#1264
The core problem this PR is trying to wrangle is that macros can expand to different stuffs, depending on context.
That is, `foo!()` on the top-level expands to a list of items, but the same `foo!()` in expression position expands to expression.
Our current `hir_parse(HirFileId) -> TreeArc<SourceFile>` does not really support this.
So, the plan is to change `hir_parse` to untyped inreface (`TreeArc<Syntaxnode>`), and add `expands_to` field to `MacroCallLoc`, such that the *target* of macro expansion is selected by the calling code and is part of macro id.
This unfortunately looses some type-safety :(
Moreover, this doesn't really fix#1264 by itself, because we die due to some other error inside macro expansion: expander fails to produce a tree with a single root, which trips assert inside rowan.

1272: Error out non single root token tree conversion r=matklad a=edwin0cheng
This PR add a check to prevent non single root token tree conversion between token trees and syntax tree.
It should prevent the assert produced in #1267.

1270: Increase Chalk solver max_size back to 4 r=flodiebold a=flodiebold
Reducing it to 2 was just a failed attempt to see whether that would help fix
some slow cases; in fact, it can create new slow cases by replacing concrete
types by variables.
