Very nice. Thanks for the work!

Patch two is fine.

Regarding patch one and three: We already have the directory
test/CodeGen and test/IslCodeGen. I propose to just leave the CLooG test
cases in test/CodeGen, but to run them conditionally.
You can add the new isl test cases to  test/IslCodeGen.

If you agree, such changes are preapproved here.
