re PR tree-optimization/85257 (wrong code with -O -fno-tree-ccp and reading zeroed vector member)
PR tree-optimization/85257
* fold-const.c (native_encode_vector): If not all elts could fit
and off is -1, return 0 rather than offset.
* tree-ssa-sccvn.c (vn_reference_lookup_3): Pass
(offseti - offset2) / BITS_PER_UNIT as 4th argument to
native_encode_expr. Verify len * BITS_PER_UNIT >= maxsizei. Don't
adjust buffer in native_interpret_expr call.
* gcc.dg/pr85257.c: New test.
