cebeedc66f Next gen IDs for functions 
The current system with AstIds has two primaraly drawbacks:

* It is possible to manufacture IDs out of thin air.
  For example, it's possible to create IDs for items which are not
  considered in CrateDefMap due to cfg. Or it is possible to mixup
  structs and unions, because they share ID space.

* Getting the ID of a parent requires a secondary index.

Instead, the plan is to pursue the more traditional approach, where
each items stores the id of the parent declaration. This makes
`FromSource` more awkward, but also more correct: now, to get from an
AST to HIR, we first do this recursively for the parent item, and the
just search the children of the parent for the matching def

dadad36bb9 Move type inlay hint truncation to language server 
This commit implements a general truncation framework for HirFormatter
that keeps track of how much has been output so far. This information
can then be used to perform truncation inside the language server,
instead of relying on the client.

Initial support is implemented for truncating types hints using the
maxInlayHintLength server config option. The existing solution in the
VSCode extension has been removed in favor of letting the server
truncate type hints.

351c29d859 Fix handling of the binders in dyn/impl Trait 
We need to be more careful now when substituting bound variables (previously, we
didn't have anything that used bound variables except Chalk, so it was not a
problem).

This is obviously quite ad-hoc; Chalk has more infrastructure for handling this
in a principled way, which we maybe should adopt.

2200: Add variables to HIR r=matklad a=matklad

Introduce a `hir::Variable`, which should cover locals, parameters and `self`. Unlike `PatId`, variable knows it's owner so it is self-contained, and should be more convenient to use from `ra_ide_api`. 

The goal here is to hide more details about `Body` from hir, which should make it easier to move `Body` into `hir_def`. I don't think that `ra_ide_api` intrracts with bodies directly at the moment anyway, but the glue layer is based basically on `ast::BindPat`, which seems pretty brittle.

This PR implements bulitin macro `line!` and add basic infra-structure for other bulitin macros:

1. Extend `MacroDefId` to support builtin macros
2. Add a `quote!` macro for simple quasi quoting.

Note that for support others builtin macros, eager macro expansion have to be supported first, this PR not try to handle it. :)

2179: Use HirDatabase to compute `is_deprecated` r=matklad a=martskins

This PR fixes #2167 by introducing `attributes_query` and adding `fn attrs(&self, def: crate::AttrDef) -> Option<Arc<[Attr]>>;`  to the `DefDatabase` trait.

I'm a little concerned about the two spots in `attributes_query` where code is repeated, but I couldn't figure out a way to avoid that, so.. I welcome suggestions 😄

2006: Improvements around `Arc<[T]>` r=matklad a=sinkuu

First commit tries to avoid cloning `Arc<[T]>` to a temporary `Vec` for mutating it, if there are no other strong references. Second commit utilizes [`FromIterator for Arc<[T]>`](https://doc.rust-lang.org/std/sync/struct.Arc.html#impl-FromIterator%3CT%3E) instead of `.collect::<Vec<_>>().into()` to avoid allocation in `From<Vec<T>> for Arc<[T]>`.

1928: Support `#[cfg(..)]` r=matklad a=oxalica

This PR implement `#[cfg(..)]` conditional compilation. It read default cfg options from `rustc --print cfg` with also hard-coded `test` and `debug_assertion` enabled.
Front-end settings are **not** included in this PR.

There is also a known issue that inner control attributes are totally ignored. I think it is **not** a part of `cfg` and create a separated issue for it. #1949

Fixes #1920

1815: Support correct `$crate` expansion in macros r=uHOOCCOOHu a=uHOOCCOOHu

This PR makes normal use cases of `$crate` from macros work as expected.

It makes more macros from `std` work. Type inference works well with `panic`, `unimplemented`, `format`, and maybe more.
Sadly that `vec![1, 2, 3]` still not works, but it is not longer an issue about macro.

18bf278c25 Handle associated type shorthand (T::Item) 
This is only allowed for generic parameters (including `Self` in traits), and
special care needs to be taken to not run into cycles while resolving it,
because we use the where clauses of the generic parameter to find candidates for
the trait containing the associated type, but the where clauses may themselves
contain instances of short-hand associated types.

In some cases this is even fine, e.g. we might have `T: Trait<U::Item>, U:
Iterator`. If there is a cycle, we'll currently panic, which isn't great, but
better than overflowing the stack...

1795: Make macro scope a real name scope and fix some details r=matklad a=uHOOCCOOHu

This PR make macro's module scope a real name scope in `PerNs`, instead of handling `Either<PerNs, MacroDef>` everywhere.

In `rustc`, the macro scope behave exactly the same as type and value scope.
It is valid that macros, types and values having exact the same name, and a `use` statement will import all of them. This happened to module `alloc::vec` and macro `alloc::vec!`.
So `Either` is not suitable here.

There is a trap that not only does `#[macro_use]` import all `#[macro_export] macro_rules`, but also imports all macros `use`d in the crate root.
In other words, it just _imports all macros in the module scope of crate root_. (Visibility of `use` doesn't matter.)

And it also happened to `libstd` which has `use alloc_crate::vec;` in crate root to re-export `alloc::vec`, which it both a module and a macro.
The current implementation of `#[macro_use] extern crate` doesn't work here, so that is why only macros directly from  `libstd` like `dbg!` work, while `vec!` from `liballoc` doesn't.
This PR fixes this.

Another point is that, after some tests, I figure out that _`macro_rules` does NOT define macro in current module scope at all_.
It defines itself in legacy textual scope. And if `#[macro_export]` is given, it also is defined ONLY in module scope of crate root. (Then being `macro_use`d, as mentioned above)
(Well, the nightly [Declarative Macro 2.0](https://github.com/rust-lang/rust/issues/39412) simply always define in current module scope only, just like normal items do. But it is not yet supported by us)

After this PR, in my test, all non-builtin macros are resolved now. (Hover text for documentation is available) So it fixes #1688 . Since compiler builtin macros are marked as `#[rustc_doc_only_macro]` instead of `#[macro_export]`, we can simply tweak the condition to let it resolved, but it may cause expansion error.

Some critical notes are also given in doc-comments.

85fdf57dbd modify tests 
Some method resolution tests now yield `{unknown}` where they did not
before.

Other tests now succeed, likely because this is helping the solver
steer its efforts.

ef2b84ddf1 introduce hir debugging infra 
This is to make debugging rust-analyzer easier.

The idea is that `dbg!(krate.debug(db))` will print the actual, fuzzy
crate name, instead of precise ID. Debug printing infra is a separate
thing, to make sure that the actual hir doesn't have access to global
information.

Do not use `.debug` for `log::` logging: debugging executes queries,
and might introduce unneded dependencies to the crate graph

Some more tweaks to #1743 to behave more like `rustc`
1. Hoist macros from `#[macro_use] extern crate`, so that they can be used before `extern crate`.
2. Implicit `#[macro_use]` for `prelude` if exists

b1a40042e8 Handle impl/dyn Trait in method resolution 
When we have one of these, the `Trait` doesn't need to be in scope to call its
methods. So we need to consider this when looking for method
candidates. (Actually I think the same is true when we have a bound `T:
some::Trait`, but we don't handle that yet).

At the same time, since Chalk doesn't handle these types yet, add a small hack
to skip Chalk in method resolution and just consider `impl Trait: Trait` always
true. This is enough to e.g. get completions for `impl Trait`, but since we
don't do any unification we won't infer the return type of e.g. `impl
Into<i64>::into()`.

6cfdfdecba Add representations of associated types 
This adds three different representations, copied from the Chalk model:
 - `Ty::Projection` is an associated type projection written somewhere in the
   code, like `<Foo as Trait>::Bar`.
 - `Ty::UnselectedProjection` is similar, but we don't know the trait
   yet (`Foo::Bar`).
 - The above representations are normalized to their actual types during type
   inference. When that isn't possible, for example for `T::Item` inside an `fn
   foo<T: Iterator>`, the type is normalized to an application type with
   `TypeCtor::AssociatedType`.
