	* ruby_atomic.h: use __atomic builtin functions supported by GCC.
	  __sync family are legacy functions now and it is recommended
	  that new code use the __atomic functions.
	  http://gcc.gnu.org/onlinedocs/gcc/_005f_005fatomic-Builtins.html

	* configure.in: check existence of __atomic functions.

	* ruby_atomic.h: define ATOMIC_SIZE_CAS() with
	  __atomic_compare_exchange_n() and refactoring.

	* ruby_atomic.h: remove duplicate definisions between ATOMIC_XXX
	  and ATOMIC_SIZE_XXX.
