Rollup merge of #87013 - FabianWolff:issue-83921, r=estebank
Fix several ICEs related to malformed `#[repr(...)]` attributes This PR fixes #83921. #83921 actually contains two related but distinct issues (one of them incorrectly reported as a duplicate in https://github.com/rust-lang/rust/issues/83921#issuecomment-814640734): In the first, a call to `delay_span_bug` leads to an ICE when compiling with `-Zunpretty=everybody_loops` (and some other pretty-printing modes), because the corresponding error is emitted in a later pass, which does not run when only pretty-printing is requested. The second issue is about parsing `#[repr(...)]` attributes. Currently, all of the following cause an ICE when applied to a struct/enum: ```rust #[repr(packed())] #[repr(align)] #[repr(align(2, 4))] #[repr(align())] #[repr(i8())] #[repr(u32(42))] #[repr(i64 = 2)] ``` I have fixed this by expanding the well-formedness checks in `find_repr_attrs()`.
