rev 3708 : 8000244: G1: Ergonomically set MarkStackSize and use virtual space for global marking stack Summary: Set the value of MarkStackSize to a value based on the number of parallel marking threads with a reasonable minimum. Expand the marking stack if we have to restart marking due to an overflow up to a reasonable maximum. Allocate the underlying space for the marking stack from virtual memory.
