    Fix missed CSE with a BLKmode entity

    The following fixes fallout of r10-7145-g1dc00a8ec9aeba which made
    us cautionous about CSEing a load to an object that has padding bits.
    The added check also triggers for BLKmode entities like STRING_CSTs
    but by definition a BLKmode entity does not have padding bits.

            PR tree-optimization/111751
            * tree-ssa-sccvn.cc (visit_reference_op_load): Exempt
            BLKmode result from the padding bits check.=
