atomic: prever inline asm over GCC builtins for armv7a
As per Patrick Trantham comment
http://groups.crossroads.io/r/topic/510xaadGgWVcXFdATnhAuN
the GCC __sync_*() builtins are more generic but slower than specialized
hand-written assembly for armv7a case.
Therefore, the code is reordered for prefer inline assembly for armv7a
over GCC builtins.
* src/atomic_counter.hpp:
(atomic_counter_t::add):
(atomic_counter_t::sub):
* src/atomic_ptr.hpp:
(atomic_ptr_t::xchg):
(atomic_ptr_t::cas):
Prefer armv7a specific inline asm over GCC __sync_*() builtins.
