The PTX md file goes to a lot of effort handling SC and DC movs,

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.
Hmm, that was definitely necessary at one point. I wonder what changed?
