https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106616#c0 provides hopefully
reproducible test.

GCC 13 (as of g:02c031088ac0bbf) triggers this for Linux's kallsys.c
(f9ff5644bcc04221bae56f922) for ia64.

Created attachment 56496
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=56496&action=edit
Test that started failing on 20 July 2023
Another instance of this ICE appeared in my glibc bot on 20 July; compile
ibm1008_420.i with -O2. This failure was introduced by
commit ef28aadad6e5cff3d7494f3c97d435a6579a2e2d
Author: Jan Hubicka <jh@suse.cz>
Date: Thu Jul 20 15:41:39 2023 +0200
loop-ch improvements, part 3
although I fully expect it's really the same bug as for the other testcases
discussed here and it was just some perturbation to the processing of this test
that resulted in the appearance for that test with that commit.

The issue is surely latent for long, not sure if that "new" trigger warrants to
make it a 14 regression. Anyway, ia64 -> P4.
