This removes the special casing for the "core" prelude.
Whenever a later dependency also exports a prelude, it will replace
the formerly imported prelude. The utilized prelude then depends
purely on import order.
This adds support for completion and goto definition of
types defined within the "core" crate. The core crate is
added as a dependency to each crate in the project.
The core crate exported it's own prelude. This caused
now all crates to inherit the core crates prelude instead
of the std crates. In order to avoid the problem the
prelude resolution has been changed to overwrite
an already resolved prelude if this was set to a crate
named core - in order to pick a better prelude like std.
Fixes#2199
2169: MBE: Mapping spans for goto definition r=matklad a=edwin0cheng
Currently, go to definition gives the wrong span in MBE. This PR implement a mapping mechanism to fix it and it could be used for future MBE hygiene implementation.
The basic idea of the mapping is:
1. When expanding the macro, generated 2 `TokenMap` which maps the macro args and macro defs between tokens and input text-ranges.
2. Before converting generated `TokenTree` to `SyntaxNode`, generated a `ExpandedRangeMap` which is a mapping between token and output text-ranges.
3. Using these 3 mappings to construct an `ExpansionInfo` which can map between input text ranges and output text ranges.

2194: Update crates r=matklad a=kjeremy
Removes nodrop and extra arrayvec
We have an extra crossbeam-queue and crossbeam-utils left but those should
drop once rayon accepts https://github.com/rayon-rs/rayon/pull/704

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 😄
