Auto merge of #82639 - jyn514:stable-options, r=Mark-Simulacrum

Don't pass -Z unstable-options by default for UI tests

Unconditionally passing -Z unstable-options makes it impossible to test whether an option requires unstable-options or not.

This uncovered quite a lot of bugs, I'll open issues for each. These don't strictly need to be fixed before this is merged, it just makes the diff much larger because of the changes to diagnostics.
