Returns the DIE map slot for the specified debug variable.
We delegate the request to DwarfDebug when the MDNode can be part of the type system, since DIEs for the type system can be shared across CUs and the mappings are kept in DwarfDebug.

Get string containing language specific context for a global name.
Walks the metadata parent chain in a language specific manner (using the compile unit language) and returns it as a string. This is done at the metadata level because DIEs may not currently have been added to the parent context and walking the DIEs looking for names is more expensive than walking the metadata.
