[PATCH 3/4] abg-reader.cc: Strip out WIP type tracking.

[Giuliano Procida <gprocida@google.com>]

This functionality was needed only for early canonicalisation of types
and is now no longer used.

	* src/abg-reader.cc (read_context): Drop m_wip_types_map
	member. Drop clear_wip_classes_map, mark_type_as_wip,
	unmark_type_as_wip and is_wip_type methods.
