[ptr-compr] Introduce StrongTaggedValue and TaggedValue ... which represent potentially compressed Object and MaybeObject values respectively. They provide methods for checking the smi/weak tags which don't require decompression and conversion to Smi/HeapObject combined with tag checks. The new classes should help to write a bit more efficient runtime (C++) code for the cases when we don't need the full decompressed value immediately. Drive-by-fix: fix ptr-compr build after Object::operator->() removal.
