Benjamin Kramer 0deb9a9a1f Extend the GlobalObject metadata interface ...

- Make eraseMetadata return whether it changed something
- Wire getMetadata for a single MDNode efficiently into the attachment
map
- Add hasMetadata, which is less weird than checking getMetadata ==
nullptr on a multimap.

Use it to simplify code.
