Print variable scope name in DEBUG_VALUE comment. Useful in some cases. e.g.
##DEBUG_VALUE: runOnMachineFunction:this <- RDI+0
##DEBUG_VALUE: runOnMachineFunction:fn <- RSI+0
##DEBUG_VALUE: DeadDefs <- undef ## SimpleRegisterCoalescing.cpp:2706
##DEBUG_VALUE: getRegInfo:this <- [%rsp+$56]+$0
##DEBUG_VALUE: getTarget:this <- [%rsp+$56]+$0
