Rollup merge of #86932 - rylev:fix-ice-86895, r=estebank
Fix ICE when misplaced visibility cannot be properly parsed Fixes #86895 The issue was that a failure to parse the visibility was causing the original error to be dropped before being emitted. The resulting error isn't quite as nice as when the visibility is parsed properly, but I'm not sure which error to prioritize here. Displaying both errors might be too confusing. r? ```@estebank```
