Rollup merge of #115294 - compiler-errors:cycle-err, r=oli-obk
More precisely detect cycle errors from type_of on opaque

Not sure if this still needs work. Just putting it up for initial impressions, since it seems that a few people are frustrated with the increased error verbosity due to #113320.

Essentially we introduce a new sub-query for `type_of` specifically for opaques which returns a value that is able to distinguish "has errors" from "due to cycle recovery".

Fixes #115188

r? `@oli-obk`
