internal: add `as_slice` to `hir::Type`
~`remove_slice`~ `as_slice` is same as `remove_ref` but for slices.
Though there is `as_array` which I believe was named such because it also gets the length of the array, maybe. I am still shaky on the names feel free to suggest corrections.
feat: add `is_float` & `is_char` to `hir::Type`
Some useful functions we didn't have on `Type` (were present on `BuiltinType`).
Also, I am considering exposing `TyKind` with `get_kind`, let me know if that's a better idea than implementing these API extensions incrementally.
Add path of workspace root folders to status output
Hi folks! Just a quick addition to the status output. There are some colleagues of mine who use a mix of Buck and Cargo. A person spent a bit of time this past week trying to figure out there the `rust-project.json` was coming from and pointed out that `rust-analyzer: Status` could be a good place to put this information. rust-analyzer doesn't seem to record the full path of the `Cargo.toml` or the `rust-project.json`, just the root directory. While not perfect, this should be enough for people to unblock themselves on. Here's an example of `rust-analyzer: Status` on the rust-analyzer repo:
```

This feature requires the user to add a command that generates a
`rust-project.json` from a set of files. Project discovery can be invoked
in two ways:
1. At extension activation time, which includes the generated
`rust-project.json` as part of the linkedProjects argument in
InitializeParams
2. Through a new command titled "Add current file to workspace", which
makes use of a new, rust-analyzer specific LSP request that adds
the workspace without erasing any existing workspaces.
I think that the command-running functionality _could_ merit being
placed into its own extension (and expose it via extension contribution
points), if only provide build-system idiomatic progress reporting and
status handling, but I haven't (yet) made an extension that does this.
internal: Rename `hir::diagnostics::MissingMatchArms.match_expr` field
`hir::diagnostics::MissingMatchArms.match_expr` had confusing name: it is pointing to scrutinee expression. Renamed to `scrutinee_expr` and used better fitting type for it.
Also small refactorings/cleanup.
fix: Watch both stdout and stderr in flycheck
Fixes#14217
This isn't great because it un-mixes the messages from the two streams, but maybe it's not such a big problem?
Load proc-macros for rustc_private crates
If the client support our server status notification there is no need to show the pop up for workspace fetching failures since that's already going to be shown in the status.

fix: show diagnostic for } token followed by else in let else statement
fix#14221
My thinking is to check if the `expr` after `=` is block like when parse `let ... lese` , and if so, emit error.
MIR episode 2
This PR adds:
1. `need-mut` and `unused-mut` diagnostics
2. `View mir` command which shows MIR for the body under cursor, useful for debugging
3. MIR lowering for or-patterns and for-loops
internal: Re-use the resolver in `InferenceContext` instead of rebuilding it whenever needed
This reduced inference time on my local build by roughly ~1 sec (out of like 60)
internal: Handle fields called as method calls as the fields they resolve to
Confusing PR title tbf but this makes it so `bar` in `foo.bar()` resolves to the field if it exists and no method with the same name exists. Improves UX slightly when incorrectly calling a field.
