Reviewers: Erik Corry,
Description:
Basic implementation of incremental marking.
Based on classic tri-color abstraction (white --- not seen, grey --- seen
and in
the marking stack, black --- seen and scanned) with a write barrier that
transfers black objects to grey when we assign to white object into field.
Currently write-barrier is out-lined (generated code just calls C function)
so
write-intensive applications are expected to show significant degradation.
