tree-optimization/121320 - UBSAN error in ao_ref_init_from_vn_reference

The multiplication by BITS_PER_UNIT should be done in poly_offset_int.

PR tree-optimization/121320
* tree-ssa-sccvn.cc (ao_ref_init_from_vn_reference): Convert
op->off to poly_offset_int before multiplying by
BITS_PER_UNIT.

(cherry picked from commit ff6f7d8e005ae94ffd55f1dba727e28531c3daf3)
