Remove usage of std::vector and getArguments from getTokenArgumentFunction ( #3435 )

getTokenArgumentFunction can be called many many times, and the vector
is not needed, but it can become quite costly.
This patch replaces getArguments with a function simply returning the
position of the token, if it is found in the arguments (thus saving the
cost of std::vector).
