https://github.com/abhina-sree created https://github.com/llvm/llvm-project/pull/113627
This is to address the latest lit regressions https://lab.llvm.org/buildbot/#/builders/64/builds/1285 caused by using the internal lit shell. This change will limit using the internal lit shell to TableGen on AIX so we do not hit these regressions.
