Work around ICEs during cross-compilation for target, ast, & attr This applies the fix for rust-lang#72003 to work around rust-lang#56935 to three more libraries. With these additional fixes, I'm able to use rustfmt_lib from wasm (rust-lang/rustfmt#4132 (comment)), which was my goal. To get it working locally and to test, I copied the `.cargo/registry/src` and applied the fix and replaced the reference in my project: ``` toml [replace] "rustc-ap-rustc_span:656.0.0" = { path = "../rustc-ap-rustc_span" } "rustc-ap-rustc_target:656.0.0" = { path = "../rustc-ap-rustc_target" } "rustc-ap-rustc_ast:656.0.0" = { path = "../rustc-ap-rustc_ast" } "rustc-ap-rustc_attr:656.0.0" = { path = "../rustc-ap-rustc_attr" } ```

…ustc-index, r=matthewjasper Apply workaround from rust-lang#72003 for rust-lang#56935 to allow for cross-compilation of `rustc_index` crate This patch applies the same workaround as rust-lang#72003 to the `rustc_index` crate. This allows recent versions of rustfmt to compile to wasm again. Related: rust-lang#72017.

This fixes #71998 by applying the work-a-round. The root cause is probably #56935, as @petrochenkov pointed out.
I reproduced the bug by:
Adding this line fixes it.
