Add new warning message for misuse of a literal as output argument

We would like to get warning messages issued, when a literal is passed as argument, which was explicitly declared as inOut or outOnly. The compiler handles this correct, but of course, the output value is lost. From our point of view, such code is wrong for outOnly as well as for inOut, if explicitly declared with it. 

So for the given example code in the attached LIT2OUT.txt compiler listing, we like to get the following:

- New warning issued for the literal used for outOnly at statement 14 on line 17.0.
- New warning issued for the literal used for explicitly declared inOut at statement 12 on line 15.0
- Nothing for the literal used for inOut by default at statement 10 on line 13.0

Please provide that in version 6.1.

    This would be useful in detecting possibly erroneous code. This has been delivered via an APAR/PTF to the 6.1 compiler.
