Reviewers: ulan, Igor Sheludko,
Description:
Eliminate invalid pointers in store buffer after marking.
The store buffer can contain stale store buffer entries, i.e., slot in dead
objects pointing to new space objects. These slots are treaded as live slots
which cause problems with non-pointer fields and makes concurrent sweeping
complicated. Removing these pointers from the store buffer before it is used
makes life easier.
