Description Terrence Cole [:terrence] 2011-12-15 15:40:31 PST
For incremental barriers we check if compartment()->needsBarrier to defer the cost when we are not in a GC cycle.  We cannot do this for cross-generation barriers.  We need to remove the checks on the post barriers and rename the enum to something  more specific.

The changes to flatten are straightforward.  I do not think we need pre barriers on init, but do let me know if I am mistaken here.
