Reviewers: Erik Corry,
Description:
Provide baseline for experimental GC implementation.
(Third attempt).
- Remove anything related to mark-compact collection;
- Guard current write-barrier implementation with
ENABLE_CARDMARKING_WRITE_BARRIER on all platforms to disable. Conditional
compilation was used instead of flag to detect all places where we emit
write-barrier. Some of them depend on actuall instructions sequence used
inside
write-barrier.
