Original source of the changes: https://github.com/jdoerfert/llvm-project/commit/12137687ee86e827f61ea8f1bfa98b050a7b3cae#diff-a6c8db9d350ec59f4eb93f27f29468b01c9590426a11c9cb79e499bc96b28adc

Rebase assumptions taken by me (Dominik Adamski):

1. Patch depends on: https://reviews.llvm.org/D156423
2. Johannes version of create parallel should be used only for offload pragmas
3. The code generated by OMPIRBuilder::createParallel depends on the OMPIRBuilder config. If OpenMPIRBuilder is configured to generate GPU code then it will generate GPU parallel version of the parallel pragma
4. Johannes changes in llvm/lib/Transforms/Utils/CodeExtractor.cpp are upstreamed

Status of the draft:

1. No additional tests
2. Not finished: createTargetWorkshareLoop
