The patch llvm#102460 already implements separate DT/LI/SE for parallel sub function. Crashes have been reported while region generator tries using oringinal function's DT while creating new parallel sub function due to checks in llvm#101198. This patch aims at fixing those cases by switching the DT/LI while generating parallel function using Region Generator. Fixes llvm#117877
