src/objects.h:5671: static const int kRetainingCounterStart =
kSlackTrackingCounterEnd - 1;
This counter will be used in future CL.
Description:
Refactor Map::ConstructionCount.
This combines Map::DoneInobjectSlackTracking and Map::ConstructionCount
into one
more generic 4-bit counter.
Counter values from 15 down to 8 are used for in-object slack tracking,
values
from 7 down to 0 are free to be used for a new counter when in-object slack
tracking is inactive.
