re PR tree-optimization/49770 (wrong code with -fno-tree-forwprop)

PR tree-optimization/49770
* tree-ssa-sccvn.c (valueize_refs_1): Return whether we
valueized any operand. Renamed from ...
(valueize_refs): ... this. New wrapper around valueize_refs_1.
(valueize_shared_reference_ops_from_ref): Return whether we
valueized any operand.
(vn_reference_lookup): Only when we valueized any operand
use the valueized reference for alias analysis. Do not preserve
the original reference tree in this case.
* g++.dg/torture/pr49770.C: New testcase.
