      Immediately promote marked objects during scavenge · dc78e0d4
      hlopko authored
      It happens that a scavenger runs during incremental marking. Currently scavenger does not care about MarkCompact's mark bits. When an object is alive and marked, and at least one scavenge happens during incremental marking, the object will be copied once to the other semispace in the new_space, and then once to the old_space. For surviving objects this is useless extra work.
      
      In our current attempts (https://codereview.chromium.org/1988623002) to ensure marked objects are scavenged, all marked objects will survive therefore there will be many objects which will be uselessly copied.
      
      This cl modifies our promotion logic so when incremental marking is in progress, and the object is marked, we promote it unconditionally.

      [heap] Get rid of the wrapper in remembered-set.h · 3ddb2249
      ahaas authored
      This patch moves the wrapper code from the remembered-set to the
      scavenger and the mark-compact code.
      
      The wrapper code inspected a slot address to see if the object that
      belongs to the address is in the from-space. If it was in the
      from-space, then some callback was executed on the object. If the object
      got move to the to-space, then the wrapper returned KEEP_SLOT, otherwise
      REMOVE_SLOT.
      
      This logic does not really belong to the remembered set, so I moved it
      away from there.
