[AArch64] Fix predicate and constraint mismatch in logical atomic operations

2014-11-04  Michael Collison <michael.collison@linaro.org>

	* config/aarch64/iterators.md (lconst_atomic): New mode attribute
	to support constraints for CONST_INT in atomic operations.
	* config/aarch64/atomics.md
	(atomic_<atomic_optab><mode>): Use lconst_atomic constraint.
	(atomic_nand<mode>): Likewise.
	(atomic_fetch_<atomic_optab><mode>): Likewise.
	(atomic_fetch_nand<mode>): Likewise.
	(atomic_<atomic_optab>_fetch<mode>): Likewise.
	(atomic_nand_fetch<mode>): Likewise.
