Rollup merge of #142923 - folkertdev:min-function-alignment-no-attributes, r=workingjubilee
fix `-Zmin-function-alignment` on functions without attributes tracking issue: https://github.com/rust-lang/rust/issues/82232 related: https://github.com/rust-lang/rust/pull/142854 The minimum function alignment was skipped on functions without attributes (because the logic was in a loop that only runs if there is at least one attribute). The underlying reason we didn't catch this before is that in our testing we generally apply `#[no_mangle]` to functions that are tested. I've added a test now that deliberately has no attributes. r? `@workingjubilee`
