I'm just not sure what test coverage the Neoverse V2 file brings.

I assume the goal of having both files (Neoverse V2 and Grace) is to ensure that we don't enable the crypto features added in this patch if `/proc/cpuinfo` doesn't list them. But there are already other mock cpuinfo files in `clang/test/Driver/Inputs/cpunative` that don't contain them, so I think we should already have coverage for those cases. Do you see what I mean?
