the simple function Arena::inc_bytes_allocated can be found as CPU consuming when profiling the fastdbg build. It is located in a cpp file.
It should better get inlined to improve the performance of the fastdbg VM which is important for complex tests.
In addition, atomic 8-Byte load and store functions are available on all platforms, so the "#if defined ..." can get removed.

Here's my proposal:

Feedback is welcome.
