7103665: HeapWord*ParallelScavengeHeap::failed_mem_allocate(unsigned long,bool)+0x97
Summary: Make sure that MutableNUMASpace::ensure_parsability() only calls CollectedHeap::fill_with_object() with valid sizes and make sure CollectedHeap::filler_array_max_size() returns a value that can be converted to an int without overflow
