        PR lto/41664
        * tree-ssa-alias.c (refs_may_alias_p_1): Canonicalize
        pointer-vs-decl case by swapping refs.  Handle some cases
        of pointer-vs-decl disambiguations more conservatively.
        * cfgexpand.c (gimple_expand_cfg): Set gimple_df->in_ssa_p
        to false after expanding.
