New testcase for uninit

The following adds a testcase that illustrates a defect in
compute_control_dep_chain and its attempt to identify loop
exits as special to continue walking post-dominators but failing
to do so for following post-dominators.  On trunk there is now
simple_control_dep_chain saving the day, avoiding the false
positive but with GCC 12 we get a bogus diagnostic.
