PTAL
Description:
Reland of Remove slots that point to unboxed doubles from the
StoreBuffer/SlotsBuffer.
The problem is that tagged slot could become a double slot after migrating
of an
object to another map with "shifted" fields (for example as a result of
generalizing immutable data property to a data field).
This CL also adds useful machinery that helps triggering incremental write
barriers.
