This bug was not resolved in time for the 12.0.0 release, so it will have to wait for 12.0.1.

If you feel this is a high-priority bug that should be fixed for 12.0.0, please re-add release-12.0.0 to the Blocks field and add a comment explaining why this is high-priority.

[llvmbot]

It seems that this was fixed for 13.x.
