I think I got this now. I will test it tonight myself if nobody tells me it
is fine as it is.

I just applied this patch and I get the following compile error:

error: member reference type 'polly::Dependences' is not a pointer
       D->getDependences(Dependences::TYPE_RAW | Dependences::TYPE_WAW |
1 error generated

If I fix this one, many CLooG test cases fail with:

/home/grosser/Projects/polly/tools/src/cloog/isl/isl_ctx.c:245: isl_ctx
freed, but some objects still reference it 0  libLLVMSupport.so
0x00007f0ac46dc1ce llvm::sys::PrintStackTrace(_IO_FILE*) + 46

I think you really need to compile and test your code before submitting (I
know this adds overhead. If we get the OpenMP patches, we can remove the
dependency to CLooG entierly)

I also looked over the patch. It looks like a very nice cleanup.
