Adds exception related arguments to the driver command arguments.
There's a master flag, -fexceptions and also language specific flags to enable/disable C++ and Objective-C exceptions. This makes it possible to for example disable C++ exceptions but enable Objective-C exceptions.

This is a helper function for validating the optional refinement step parameter in reciprocal argument strings.
Return false if there is an error parsing the refinement step. Otherwise, return true and set the Position of the refinement step in the input string.
