BlockId: remove BlockMap and BlockSet synonyms
This continues removal of `BlockId` module in favor of Hoopl's `Label`. Most of the changes here are mechanical, apart from the orphan `Outputable` instances for `LabelMap` and `LabelSet`. For now I've moved them to `cmm/Hoopl`, since it's already trying to manage all imports from Hoopl (to avoid any collisions).
