LOG: [CodeGen] Forward-declare TargetMachine (NFC)

InstrEmitter.h needs TargetMachine but relies on a forward declaration
of TargetMachine in MachineOperand.h.  This patch adds a forward
declaration right in InstrEmitter.h.

While we are at it, this patch removes the one in MachineOperand.h,
where it is unnecessary.

Added: 
    

Modified: 
    llvm/include/llvm/CodeGen/MachineOperand.h
    llvm/lib/CodeGen/SelectionDAG/InstrEmitter.h

Removed:
