PATCH [5/10] arm: Extend again arm_feature_set struct to provide more bits

Browse Source 
include/
2021-06-11  Andrea Corallo  <andrea.corallo@arm.com>

	* opcode/arm.h (arm_feature_set): Extend 'core' field.
	(ARM_CPU_HAS_FEATURE, ARM_FSET_CPU_SUBSET, ARM_CPU_IS_ANY)
	(ARM_MERGE_FEATURE_SETS, ARM_CLEAR_FEATURE, ARM_FEATURE_EQUAL)
	(ARM_FEATURE_ZERO, ARM_FEATURE_CORE_EQUAL): Account for
	'core[2]'.
	(ARM_FEATURE_CORE_HIGH_HIGH): New macro.
