In this patch we discard the scops where entry and exit are the same BB.
This is an effort to remove graphite-scop-detection.c:limit_scops.
Removing the limit_scops function introduces correctness regressions.
We are making relevant changes in incremental steps to fix those bugs,
and finally we intend to remove limit_scops.
