[AArch64] Fix ARMv8.1 and ARMv8.2 feature settings.
ARMv8.1 includes CRC as a required extension but this isn't reflected in
the features enabled by -march=armv8.1-a. The FP16 feature modifier also
clashes with AARCH64_FEATURE_V8_1 and the list of features for ARMv8.2
is missing ARMv8.1 features.
This patch enables +crc for -march values of armv8.1-a and later. It
also fixes the values for AARCH64_FEATURE_F16 and makes
AARCH64_ARCH_V8_2 and superset of AARCH64_ARCH_V8_2.
