GlobalISel: forbid physical registers on generic MIs.
We're intending to move to a world where the type of a register is determined by its (unique) def. This is incompatible with physregs, which are untyped. It also means the other passes don't have to worry quite so much about register-class compatibility and inserting COPYs appropriately. llvm-svn: 280132
