Replace {{HostAsm::atomicAdd}} and {{AtomicInc}} with
{{[std::atomic|http://en.cppreference.com/w/cpp/atomic/atomic]}}.

> the compiler to choose the code or instructions that optimize the behavior

> replaced with C++11 standard functions.
> Some Examples:
> On Solaris SPAC we have inline assembly.
> On Solaris x86 we use Solaris specific runtime functions.
> On Windows we use really old Win32 functions that have some non-standard
> behavior.

Replace {{SpinLock}} class with C++11 style
{{[BasicLockable|http://en.cppreference.com/w/cpp/concept/BasicLockable]}}
class, {{spinlock_mutex}}. You can find several public domain examples of how
to implement a {{spinlock_mutex}} that can be used with
{{[std::lock_guard|http://en.cppreference.com/w/cpp/thread/lock_guard]}}.
