Part of the bid to have each piece of the runtime be separately compilable.  The BlkAttr flag values were defined in the spec, so each portion of the runtime just defined them.  I've since relaxed on this goal though and now think it's okay for everything to import whatever is in core, so the compiler runtime code could import core.memory and use that instead.
