This patch provides infrastructure to pin object types to specific spaces. This allows embedders to create mutual exclusive arenas for certain (base) types. In future, this will also be used to provide sliding-window compaction on certain custom spaces. We mainly preserve the existing infrastructure with the difference that spaces are now slightly more dynamic than in Blink as they are kept in a vector instead of a fixed-size array. The mechanism differs from Blink in that it does not allow the user object to call allocation methods directly but instead provides a trait that can be overridden to specify a custom space. The patch preserves templatization for objects that do not go into custom spaces to safe a branch in the allocation hot path.
