Currently there are many places where an aarch64_feature_flags variable is used, but only the bottom three isa mode bits are set and read. Using a separate data type for these value makes it more clear that they're not expected or required to have any of their upper feature bits set. It will also make things simpler and more efficient when we extend aarch64_feature_flags to 128 bits. This patch uses explicit casts whenever converting from an aarch64_feature_flags value to an aarch64_isa_mode value. This isn't strictly necessary, but serves to highlight the locations where an explicit conversion will become necessary later. gcc/ChangeLog: * config/aarch64/aarch64-opts.h: Add aarch64_isa_mode typedef. * config/aarch64/aarch64-protos.h (aarch64_gen_callee_cookie): Use aarch64_isa_mode parameter.
