MO_VirtualRegister but if the register number is one of a physical
register is it considered as a physical register.

more of a testcase for profiling information than anything that should reasonably
be used, but it's a starting point.  When I have more time I will whip this into
better shape.

MO_VirtualRegister but actually be representing a physical register.

Having a proper 'select' instruction would allow the elimination of a lot
of the special case cruft in this patch, but we don't have one yet.

Remove long obsolete method.  switch instructions are first class entities in the CFG, and have been for a LOOOONG time.

methods which have strangely different semantics in different backends,
and noone knew what any did.

Getting rid of these ALSO allows the dependence of MachineInstr.h on
MRegisterInfo.h to be removed, which makes me much happier, and probably
alkis too.  :)
