presently NYI's.  The implementation is pretty straightforward.  One catch: vstr/vldr don't have an update mechanism, so I'm forced to use the store multiple/load multiple variants.  There was also a bug where the mode (up, down) of the store was not recorded.

whoops, the definition of vpush and vpop was in a later patch.

Nit: double indented?

Branching over a breakpoint -- did you want to leave this in?
