cec5c20656 7033292: G1: nightly failure: Non-dirty cards in region that should be dirty 
The epochs on the card cache array are initialized to 0 and our initial epoch also starts at 0. So, until the first GC, it might be possible to successfully "claim" a card which was in fact never initialized.

3e9fe24ddd 7023069: G1: Introduce symmetric locking in the slow allocation path 
7023151: G1: refactor the code that operates on _cur_alloc_region to be re-used for allocs by the GC threads
7018286: G1: humongous allocation attempts should take the GC locker into account

First, this change replaces the asymmetric locking scheme in the G1 slow alloc path by a summetric one. Second, it factors out the code that operates on _cur_alloc_region so that it can be re-used for allocations by the GC threads in the future.

c2275649b7 7026932: G1: No need to abort VM when card count cache expansion fails 
Manage allocation/freeing of the card cache counts and epochs arrays directly so that an allocation failure while attempting to expand these arrays does not abort the JVM. Failure to expand these arrays is not fatal.

3e02204f5d 7029036: Card-table verification hangs with all framework collectors, except G1, even before the first GC 
When verifying clean card ranges, use memory-range-bounded iteration over oops of objects overlapping that range, thus avoiding the otherwise quadratic worst-case cost of scanning large object arrays.
