SYSDEBUG to fully support OPT(2) or OPT(3)

When the PL/I compiler is performing optimization, it has the ability to move statements in the resulting executable.
When this happens, the backwards traceability to the actual written source statement is lost.
The information is avaiable in the compiler listing.
But it is not persisted into the SYSDEBUG file.

    It is not likely that this requirement will be implemented in the next 2-4 years and so it is being declined at this point. The requirement will be kept in the RFE system and might be reassessed in the future.

    Under optinmization the meaning of a statement is very tenuous: individual instructions generated in support of any one statement are moved around to optimize performance, code from statements is merged, statements are deleted, etc etc. Even many variables have questionable meaning. They may spend all or part of their lives in one or more registers, etc. But this is a good goal

    Fault Analyzer should already support opt(2) ?
