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.
