[AArch64] Add ACLE arch-related predefined macros

Browse source 
2014-11-06  Renlin Li  <renlin.li@arm.com>

	* config/aarch64/aarch64.c (aarch64_architecture_version): New.
	(processor): New architecture_version field.
	(aarch64_override_options): Initialize aarch64_architecture_version.
	* config/aarch64/aarch64.h (TARGET_CPU_CPP_BUILTINS): Define __ARM_ARCH,
	__ARM_ARCH_PROFILE, aarch64_arch_name macro.
