AD - Program call graph for DL1 resource can be improved for certain ROLB scenario.

When IMS online program has the direct ROLB call without being accessing database segments, then AD call graph is shown as if program access multiple segments from the DBD. It looks to be little misleading from user aspect though the order of IMS-DB PCB'es are controlled by optional settings (NONE/CICSDBCTL or BMP or Batch depending on CMPAT parameter YES or NO) in build client. 

This issue was spotted in one of the live IDz/ADDI education to internal users.

Details:

Eg: Program PGM1 has direct ROLB call
