Change 64 bit atomic counter to size_t There was a 64 bit cas that was showing up as very expensive on 32 bit X86. The counter was for Region::objects_allocated_. This change moves it to be size_t. X86 GC time: 13.6s -> 11.1s X86 perf: ConcurrentCopying::Copy 14.07% -> 3.73% of samples Benchmark score unmeasured.
