Will Newton Oct. 17, 2014, 3:31 p.m.
Switch the AArch64 port to using the generic GCC intrinsic based
atomic implementation.

ChangeLog:

2014-10-15  Will Newton  <will.newton@linaro.org>

	* sysdeps/aarch64/bits/atomic.h
	(__ARCH_ATOMIC_64_SUPPORTED): Define to 1.
	Include sysdeps/generic/atomic_types.h.
	Include sysdeps/generic/atomic.h.
	Remove existing atomic defines and tyepdefs.
