aarch64: Extract Condition flag manipulation feature from Armv8.4-A
Extract FLAGM (Condition flag manipulation) feature from Armv8.4-A.
Please note that FLAGM stays a Armv8.4-A feature but now can be
assigned to other architectures or CPUs.
New -march option +flagm is added to enable independently this
feature.
