Via greping, I find that it is only used in XXXTargetMachine class.
Obviously its codes overlap with those in XXXELFObjectWriter class.
In consideration of those codes in XXXAsmPrinter class which print out
MachineInstr in .s format, I tend to think they are old codes that
might be obsolete and will be replaced with MC layer implementation,
but I am not sure.
Hope someone authoritative answer this question.
