terminators to use virtual registers, and update phi elimination to correctly
update livevar when eliminating phi's.  This fixes a problem on a testcase

GCC has a bug (24907) in which is fails to catch this, but VC++ correctly
notes its illegality, so tblgen must be taught to only generate legal C++.
