Move MOTy::UseType enum into MachineOperand. This eliminates the
...
switch statements in the constructors and simplifies the
implementation of the getUseType() member function. You will have to
specify defs using MachineOperand::Def instead of MOTy::Def though
(similarly for Use and UseAndDef).

* Fix bug in the createNOP method, which was not marking the operands of the
generated XCHG as useanddef. I don't think this method is actually used,
so it wasn't breaking anything, but it should be fixed anyway...
