Suggest valid crate type if invalid crate type is found
This adds a suggestion to the `invalid_crate_types` lint.
The suggestion is based on the Levenshtein distance to existing crate
types. If no suggestion is found it will show the lint without any
suggestions.
Closes#53958

Add rustc SHA to released DWARF debuginfo
This commit updates the debuginfo that is encoded in all of our released
artifacts by default. Currently it has paths like `/checkout/src/...` but these
are a little inconsistent and have changed over time. This commit instead
attempts to actually define the file paths in our debuginfo to be consistent
between releases.
All debuginfo paths are now intended to be `/rustc/$sha` where `$sha` is the git
sha of the released compiler. Sub-paths are all paths into the git repo at that
`$sha`.
Stabilization change for mod.rs
This change is in response to https://github.com/rust-lang/rust/issues/53125.
The patch makes the feature accepted and removes the tests that tested the
non-accepted status of the feature.
support ascription for patterns in NLL
This implements the strategy outlined in [this comment](https://github.com/rust-lang/rust/issues/47184#issuecomment-416669986):
- We first extend the NLL subtyping code so it can handle inference variables and subtyping.
- Then we extend HAIR patterns with type ascription.
- Then we treat the type `T` in `let pat: T = ...` as an ascription.
Before landing, a few things:
- [x] Fix the WF rule bug (filed a FIXME https://github.com/rust-lang/rust/issues/54105)
- [x] Fix an ICE I encountered locally around bound regions, or else file a follow-up
- [x] More tests probably =)

For some weird reason this fixes `intrinsic-move-val`. It also affects
various test heuristics. I removed one test (`reborrow_basic`) that
didn't seem to really be testing anything in particular anymore,
compared to all the other tests we've got.
rustc_resolve: inject `uniform_paths` canaries regardless of the feature-gate, on Rust 2018.
This PR is an attempt at future-proofing "anchored paths" by emitting the same ambiguity errors that `#![feature(uniform_paths)]` would, with slightly changed phrasing (see added UI tests).
Also, on top of #54005, this PR allows this as well:
```rust
use crate_name;
use crate_name::foo;
```
In that any ambiguity between an extern crate and an import *of that same crate* is ignored.

#53359: putting multiple unresolved import on single line
r? @estebank
Here is WIP implementation of #53359
this PR have clubbed multiple unresolved imports into a single line.
I think still two things need to improve like giving specific `label message` for each span of multi_span(how we can do this?) and second we are getting a warning while compiling, stating something like `E0432` have been passed before.
