History
Jakob Stoklund Olesen 7ebc4d63db Add MachineInstr::readsVirtualRegister() in preparation for proper handling of 
partial redefines.

We are going to treat a partial redefine of a virtual register as a
read-modify-write:

  %reg1024:6 = OP

Unless the register is fully clobbered:

  %reg1024:6 = OP, %reg1024<imp-def>

MachineInstr::readsVirtualRegister() knows the difference. The first case is a
read, the second isn't.
