The streaming and vector size properties come from function attributes, so they need to be passed to the subtarget when constructing it in `AArch64TargetMachine::getSubtargetImpl(const Function &)`.
For the option in this PR there is no corresponding function attribute and therefore no need for the indirection, so it makes sense to move the option to AArch64Subtarget.cpp.
