  Log Message:
  -----------
  [MC] Add baseline test for MCContext::getSubtargetCopy HwMode loss

No change intended here, just adding test coverage showing that
MCContext::getSubtargetCopy currently slices away the target's
<Target>GenMCSubtargetInfo subclass and causes getHwMode() and
getHwModeSet() to return 0.
