They can just be written as `use rustc_foo::bar`, which is far more standard. (I didn't even know that a `crate::` prefix was valid.)
This change ignores the RUSTC_WRAPPER_REAL environment variable if it's set to the empty string. This matches cargo behaviour and allows users to easily shadow a globally set RUSTC_WRAPPER (which they might have set for non-rustc projects).
Fixes an ICE that occurred when the struct in question has an error
…Nilstrieb Remove braces when fixing a nested use tree into a single item [Back in 2019](rust-lang#56645) I added rustfix support for the `unused_imports` lint, to automatically remove them when running `cargo fix`. For the most part this worked great, but when removing all but one childs of a nested use tree it turned `use foo::{Unused, Used}` into `use foo::{Used}`. This is slightly annoying, because it then requires you to run `rustfmt` to get `use foo::Used`. This PR automatically removes braces and the surrouding whitespace when all but one child of a nested use tree are unused. To get it done I had to add the span of the nested use tree to the AST, and refactor a bit the code I wrote back then. A thing I noticed is, there doesn't seem to be any `//@ run-rustfix` test for fixing the `unused_imports` lint. I created a test in `tests/suggestions` (is that the right directory?) that for now tests just what I added in the PR. I can followup in a separate PR to add more tests for fixing `unused_lints`. This PR is best reviewed commit-by-commit.

Make sure we don't deny macro vars w keyword names `$async:ident`, etc are all valid. Fixes rust-lang#124862

Update cc crate to v1.0.97
Ignore empty RUSTC_WRAPPER in bootstrap This change ignores the RUSTC_WRAPPER_REAL environment variable if it's set to the empty string. This matches cargo behaviour and allows users to easily shadow a globally set RUSTC_WRAPPER (which they might have set for non-rustc projects). I hit this because I have RUSTC_WRAPPER set to `sccache` in my fish universal env vars, and I can only shadow those locally with an empty string, I can't unset it entirely.
