The dependencies between these new target attributes and others are also specified in llvm/include/llvm/TargetParser/AArch64TargetParser.h. And we want to support having nofp and nosimd disable jsconv and complxnum. This piece of code makes the driver pass the correct -target-feature flags to the backend.
