[AsmParser]Emit an error if a macro has two (or more) parameters sharing the same name Introducing a new error to macro parameters' parsing: currently, llvm-mc won't complain if a macro have two (or more) named params with the same name. this behavior is false, as there's no merit in having some params sharing a name. now, instead of tolerate such a phenomena - emit an appropriate error.
