print_all_lattices() suggests it is expected for unoptimized cases to have no
IPA info:
"""
info = IPA_NODE_REF (node);
/* Skip unoptimized functions and constprop clones since we don't make
lattices for them. */
if (!info || info->ipcp_orig_node)
continue;
"""
The crash happens when analysing a()->e() edge. But a() was compiled with -flto
-O0 and thus has no IPA fnsummary.
