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.

2205: Implement bulitin line! macro r=matklad a=edwin0cheng

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...

Type-relative paths (`<T>::foo`) also need to work in type context, for example
`<T>::Item` is legal. So rather than returning the type ref from the resolver
function, just check it before.
