    [heap] Add base class for LargeObjectSpaces · eb667651
    Leszek Swirski authored
    Both LO_SPACE and NEW_LO_SPACE use the basic page management system of
    LargeObjectSpace, but implement different AllocateRaw methods (with
    the NEW_LO_SPACE version shadowing the LO_SPACE version).
    
    To clean this up, and allow other future LargeObjectSpace implementations
    (in particular, an off-thread variant), refactored the current
    LargeObjectSpace into a base class, and make both LargeObjectSpace
    (renamed to OldLargeObjectSpace) and NewLargeObjectSpace extend this
    class.
