Committed as r196116.
The issue in PR56350 is two-fold. First, fix_loop_structure mishandles
latch edge computation (ugh). Second, RTL if-conversion, when merging
a latch block into sth else ends up generating stale latch block
references.
The following two patches cure that, adding some basic latch block
checking.

Hi,
in ipa-cp there is a dumping condition that was intended to trigger
