ee9c7c940c Auto merge of #120847 - oli-obk:track_errors9, r=compiler-errors
Continue compilation after check_mod_type_wf errors

The ICEs fixed here were probably reachable through const eval gymnastics before, but now they are easily reachable without that, too.

The new errors are often bugfixes, where useful errors were missing, because they were reported after the early abort. In other cases sometimes they are just duplication of already emitted errors, which won't be user-visible due to deduplication.

Bound errors span label cleanup

Consolidate span labels for "this type doesn't satisfy a bound" for more compact diagnostic output.
