e1764f907b [WIP] Make ast nodes contain span
* `struct Expr` + `enum ExprKind` -> `enum Expr`

`Expr` / `ExprKind` approach does not work well with recursive
 processing based on the type system because we can't access common
 fields like span while processing child node like `MemberExpr`.

As ast processing is inherently recursive, we should use a
 recursive-friendly approach.

 * `#[derive(FromVariants)]`
It creates lots of `From<T>` to help using ast enums as a real sum type.

 * `#[derive(Spanned)]`

Inspired by https://docs.rs/syn/0.12.13/syn/spanned/trait.Spanned.html

It does not handle attributes yet.

 * Parser is not updated yet.

fa40c8ddf3 Make rls work
rust-analysis chokes with `Option<Box<Expr>>` style fields.
Rls only shows a warning on the crate with that fields, but ICEs on
dependent crates.
This can be workarounded by using `Option<(Box<Expr>)>`.

Also, using multiple glob imports is bad for rls.
So this commit deglobs them.
