rG556ea7d2e0ba: [AArch64] Add 'apple-latest' CPU alias
rL352412: [AArch64] Add 'apple-latest' CPU alias
Summary

The 'apple-latest' alias is supposed to provide a CPU that contains the latest Apple processor model supported by LLVM.

This is supposed to be used by tools like lldb to provide a target that supports most of the CPU features.

For now, this is mapped to Cyclone.

LGTM. It might be worth to add the CPU to test/CodeGen/AArch64/cpus.ll as well.
