test case
Probably since 490659bdcf7557513 [<a href="https://reviews.llvm.org/D31386">https://reviews.llvm.org/D31386</a>] Polly
produces too lax dependences. For the attached test case there is no dependence
ordering S2 and S0 even though one reads C[i] and one writes it. The jscop
attached reorders them and it seem to pass all validity checks.</pre>
