    [heap] Reland "Use shared markbits in the concurrent marker." · 1b064d9c
    ulan authored
    The concurrent marker now colors objects grey and black using
    the atomic markbit operations.
    
    The heap visitor is changed in two ways:
    1) It iterates the map pointer of each object.
    2) It guards object visitation with a predicate, which is overridden
    in the concurrent marker with the result of GreyToBlack transition.
