Rollup merge of #142804 - zachs18:rename-layouts-to-layoutdata-in-comments, r=saethlin

Rename `LayoutS` to `LayoutData` in comments

`LayoutS` was renamed to `LayoutData`, but some comments in the compiler were not changed. This updates comments in the compiler (and one section of commented-out code in rust-analyzer) to refer to `LayoutData` instead of `LayoutS`.
