python 3 isn't supported when building llvm/clang, according to llvm's CMakeLists.txt.

Having plugins only work on custom builds of clang seems to be against the main use of plugins. (If testing is the only problem, I would gladly test it on Windows with mingw, and maybe Mac if needed)


After this patch goes in I plan to email llvm-dev/cfe-dev to see if people think that's a good idea.

Will do.
