Since interaction with the python interpreter is moving towards being more isolated, we won't be able to include this header from normal files anymore, all includes of it should be localized to the python library which will live under source/bindings/API/Python after a future patch. None of the files that were including this header actually depended on it anyway, so it was just a dead include in every single instance. llvm-svn: 238581
