API for tracking metadata references through RAUW and deletion.

Shared API for updating Metadata pointers in subclasses that support RAUW.

This API is not meant to be used directly. See TrackingMDRef for a user-friendly tracking reference.

◆ track() [2/4]

Track the reference to metadata for DebugValueUser.

As track(Metadata*&), but with support for calling back to Owner to tell it that its operand changed. This could trigger Owner being re-uniqued.

◆ track() [3/4]

Track the reference to metadata for Metadata.
