LLDB fails to build against Python 2.X, I get the following error message:
/path/to/llvm-build/src/lldb/source/Plugins/ScriptInterpreter/Python/PythonReadline.cpp:52:25:
error: use of undeclared identifier 'PyMem_RawMalloc'; did you mean
'PyMem_Malloc'?
char *ret = (char *)PyMem_RawMalloc(1);
^~~~~~~~~~~~~~~
PyMem_Malloc

PyAPI_FUNC(void *) PyMem_Malloc(size_t);

According to the Python documentation, PyMem_RawMalloc() was only introduced in
3.4: [https://docs.python.org/3/c-api/memory.html](https://docs.python.org/3/c-api/memory.html)
Looking at the cherry-picks between llvmorg-9.0.0-rc5 and llvmorg-9.0.1-rc1, I
suspect that this is caused by [https://reviews.llvm.org/D69793](https://reviews.llvm.org/D69793).
