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.
