Rebased patch (sorry for the delay). I've added fixup code for the interface change to InitSections for clang and one of the unit tests. I've also removed the [NFC] as this will likely break a lot of downstream tools using MC.

An alternative implementation that is less disruptive would make the MCSubtargetInfo an optional parameter that could be nullptr but that would mean that we'd need to test in emitNops whether the MCSubtargetInfo is nullptr which is not ideal but it may lead to a much smaller patch for this and D45962 <https://reviews.llvm.org/D45962>
