Fixes: #152280
MCP: rust-lang/compiler-team#963

I've separated the commits for easier review.

Add compiler/rustc_codegen_cranelift/scripts/filter_profile.rs to the ALLOWED list for bins, and add compiler/rustc_codegen_gcc/build_system/src/utils.rs to the unit test exclusion list.

The .patch was allowed because of this file.

    with open(output_file, "w", encoding="utf8") as out:
        out.write("""// File generated by `rustc_codegen_gcc/tools/generate_intrinsics.py`

I added // ignore-tidy-filelength here and also manually added it to compiler/rustc_codegen_gcc/src/intrinsic/archs.rs.

Because of this test, should I move the test or allow this?
It felt like a strong unit test, and I didn't see a good place for it, so I allowed it for now.

Tidy does not run inside the cg_clif and cg_gcc repos, which means whenever we do a sync, there is a fair chance that we did be forced to male changes when tidy complains.

I would suggest not running full tidy against the cg_* subtrees yeah.

Also, doesn't rust-lang/compiler-team#963 only say TODO -> FIXME? Not other tidy checks? I do not think we should be enforcing other tidy rules for the cg_* subtrees.

Ah, I overinterpreted it — my mistake. Thanks for the clarification. I’ll update it accordingly.
