f8c12980 - Test that independent block pass does not transform induction variables

Test that independent block pass does not transform induction variables The original test case showed a problem with the independet blocks pass and we decided to XFAIL it for now. Unfortunately the failure is not detected if we build without asserts and the verification of the independent block pass is not run. This change tests now for the actual reason of the failure and should trigger even in a non asserts build. We did not yet solve the underlying bug, but this should at least make the test suite behavior consistent. Merged from: https://llvm.org/svn/llvm-project/polly/trunk@183025 llvm-svn: 183384
