Jakob Stoklund Olesen 5c8eda0ebc Add MachineInstr::tieOperands, remove setIsTied(). ...

Manage tied operands entirely internally to MachineInstr. This makes it
possible to change the representation of tied operands, as I will do
shortly.

The constraint that tied uses and defs must be in the same order was too
restrictive.
