* tree-ssa-loop-ivopts.c (seq_cost): Fix call to rtx_cost
This only happens in 32 bit mode so I can't reproduce it on IA64 Linux.
If I turn off selective scheduling (-fno-selective-scheduling or
-fno-selective-scheduling2) it goes away. I don't know if the bug is in the
scheduling or in this fix to PR 45098.
