Fix double expansion of macro arguments.

Browse source 
This adds a new fullyExpanded flag that makes sure that macro arguments
only get expanded once. This can happen either in PrescanMacroArg, or, if
there is token pasting or a function-like macro name has been passed as
an argument and may need to be expanded when used as a function.
