AtomicBool: fix bug on AtomicBoolDebugView
Atomic: Added padded bool, int, long, reference and array reference to avoid false sharing by ensuring that each instance has it's own cache line. See also: http://www.drdobbs.com/parallel/eliminate-false-sharing/217500206?pgno=4
Atomic unit tests: added padded unit tests to bool, int and long
Solution: Added AtomicBenchmark on integers and longs.
