342a620a7f 6920090: G1: Disable ReduceInitialCardMarks at least until 6920109 is fixed 
G1 now answers "no" to the query can_elide_initializing_store_barrier() in the product build. A debug flag allows alternate behaviour in debug builds.

Stub code generated to call G1 barriers does not allocate spill space on the stack as required by Windows x64 ABI. The fix is to use more ABI-friendly call_VM_leaf().

29a13dc105 6915005: G1: Hang in PtrQueueSet::completed_buffers_list_length with gcl001 
When enqueuing a completed PtrQueue buffer, cache a local pointer to the buffer and clear the field in the PtrQueue prior to unlocking the mutex referenced by the _lock field and pass the cached local value to the enqueuing routine. This will prevent the same completed buffer being enqueued multiple times, which causes the hang.

331512606a 6896647: card marks can be deferred too long 
Deferred card marks are now flushed during the gc prologue. Parallel[Scavege,OldGC] and SerialGC no longer defer card marks generated by COMPILER2 as a result of ReduceInitialCardMarks. For these cases, introduced a diagnostic option to defer the card marks, only for the purposes of testing and diagnostics. CMS and G1 continue to defer card marks. Potential performance concern related to single-threaded flushing of deferred card marks in the gc prologue will be addressed in the future.
