    ByteCodeGen: use byte indexing for BCenv
    
    This is another change needed for #13825 (also based on D38 by Simon
    Marlow).
    
    With the change, we count the stack depth in bytes (instead of words).
    We also introduce some `newtype`s to help with the change.
    
    Note that this only changes how `ByteCodeGen` works and shouldn't
    affect the generated bytecode.
