5270: Add argument count mismatch diagnostic r=matklad a=jonas-schievink
Closes https://github.com/rust-analyzer/rust-analyzer/issues/4025.
This currently has one false positive on this line, where `max` is resolved to `Iterator::max` instead of `Ord::max`:
8aa10c00a4/crates/expect/src/lib.rs (L263)
(I have no idea why it thinks that `usize` is an `Iterator`)
TODO:
* [x] Tests
* [x] Improve diagnostic text for method calls

4851: Add quickfix to add a struct field r=TimoFreiberg a=TimoFreiberg
Related to #4563
I created a quickfix for record literals first because the NoSuchField diagnostic was already there.
To offer that quickfix for FieldExprs with unknown fields I'd need to add a new diagnostic (or create a `NoSuchField` diagnostic for those cases)
I think it'd make sense to make this a snippet completion (to select the generated type), but this would require changing the `Analysis` API and I'd like some feedback before I touch that.

Anchoring to the SourceRoot wont' work if the path is absolute:
#[path = "/tmp/foo.rs"]
mod foo;
Anchoring to a file will.
However, we *should* anchor, instead of just producing an abs path.
I can imagine a situation where, for example, rust-analyzer processes
crates from different machines (or, for example, from in-memory git
branch), where the same absolute path in different crates might refer
to different files in the end!
The idea behind requiring the label is a noble one, but we are not
really using it consistently anyway, and it should be easy to retrofit
later, should we need it.
