    Once the perf parameter parser reaches a non-parameter word, that means
    the command is already found and the rest of the string is the parameter
    of this command so no need to parse more.

    As an example, when we want to run
    perf stat -- ls -al
    it is obvious that the -al is the parameter of the ls command, so we
    should able to run this like
    perf stat ls -al
