This should get revisited now that we have redesigned how the back edges are
generated.
FWIW, all the back edges are removed prior to generating RTL in
gimple_expand_cfg():
/* At the moment not all abnormal edges match the RTL
representation. It is safe to remove them here as
find_many_sub_basic_blocks will rediscover them.
In the future we should get this fixed properly. */
I'll revisit this and see if we can resolve this.
