aarch64: Add support for Armv9.5-A architecture
The new -march=armv9.5-a flag enables access to the
mandatory cpa, lut and faminmax extensions.
Existing test cases for features are extended to verify they
work without additional flags.

* In x86 Intel syntax undue mnemonic suffixes are now warned about. This is
a first step towards rejecting their use where unjustified.
