Essentially the same as the GEP change in r230786.
A similar migration script can be used to update test cases, though a few more
test case improvements/changes were required this time around: (r229269-r229278)

for line in sys.stdin:

; The target lowering for integer comparisons was replacing some DAG nodes

; cycles in DAGs, and eventually crashes. This is the testcase for
