Allow any cl::opt to use the method getPosition() to retrieve the option's
absolute position on the command line. Similarly allow any cl::list to
use the method getPosition(n) to retrieve the absolute position of the nth
option in the list. This provides support for two things: (a) options like
-l that are actually positional and their order of occurrence matters when
they are intermixed with positional arguments like "a.o"; and (b) options
like -x LANG which affect only the positional arguments that come after
the option. In both cases, knowing the absolute position of a given option
helps.
