2014-10-15  Renlin Li <renlin.li@arm.com>

	* config/aarch64/aarch64.h (TARGET_CPU_CPP_BUILTINS): Define
	__ARM_BIG_ENDIAN, __ARM_SIZEOF_MINIMAL_ENUM. Add __ARM_64BIT_STATE,
	__ARM_ARCH_ISA_A64, __ARM_FEATURE_CLZ, __ARM_FEATURE_IDIV,
	__ARM_FEATURE_UNALIGNED, __ARM_PCS_AAPCS64, __ARM_SIZEOF_WCHAR_T.
