Detailed Description

Creates and manages DebugObjects for JITLink artifacts.

DebugObjects are created when linking for a MaterializationResponsibility starts. They are pending as long as materialization is in progress.

There can only be one pending DebugObject per MaterializationResponsibility. If materialization fails, pending DebugObjects are discarded.

Once executable code for the MaterializationResponsibility is emitted, the corresponding DebugObject is finalized to target memory and the provided DebugObjectRegistrar is notified. Ownership of DebugObjects remains with the plugin.
