Test case to report this bug

This attached test case causes with r248663 an 'isl_ctx freed, but some objects
still reference it' error, when called with:

polly-opt -polly-scops /tmp/schedule-not-freed.ll -analyze
-polly-detect-unprofitable

This bug is the reason for several of the compile-time failures we see in our
new buildbot:
