    [ptr-compr] Introduce StrongTaggedValue and TaggedValue · ae348e30

    ... 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.
