* tree-ssa-alias.h (enum translate_flags): New.
(get_continuation_for_phi): Use it instead of simple bool flag.
(walk_non_aliased_vuses): Likewise.
* tree-ssa-alias.c (maybe_skip_until): Adjust.
(get_continuation_for_phi): When looking across backedges only
disallow valueization.
(walk_non_aliased_vuses): Adjust.
* tree-ssa-sccvn.c (vn_reference_lookup_3): Avoid valueization
if requested.
* gcc.dg/tree-ssa/ssa-fre-81.c: New testcase.
