Given you're cleaning this up, please move the `ForceStreamingCompatible` abstraction into `AArch64TargetMachine::AArch64TargetMachine`.  You'll see we ended up doing the same for the sve-vector-bits handling so the command line option controls the creation of subtarget rather than needing to overriding its state like done here.

Although this'll make the patch non-NFC, I argue that's already the case given the PR is already removing one command line option to introduce a new one.
