7ecfe0a839 A big X86 instruction rename. The instructions are renamed to make 
their names more decriptive. A name consists of the base name, a
default operand size followed by a character per operand with an
optional special size. For example:

ADD8rr -> add, 8-bit register, 8-bit register

IMUL16rmi -> imul, 16-bit register, 16-bit memory, 16-bit immediate

IMUL16rmi8 -> imul, 16-bit register, 16-bit memory, 8-bit immediate

MOVSX32rm16 -> movsx, 32-bit register, 16-bit memory

7f7d70a53c 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).

128b75130d * Start using tablegen'd instruction descriptions 
* 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...
