The PTX md file goes to a lot of effort handling SC and DC movs, including for
unspecs to mov low and high parts around. However, these code paths are not
exercised in any gcc test or the build of newlib. The generic handling of these
movs deals with type punning, (using the stack frame, if needed). There
doesn't appear a need for a separate punbuffer.
Thus this patch deletes a lot of that machinery.
