Either this, or must be the same as the machine scalar used in the
previous component (but of course this component might increase the size
of the required machine scalar; eg, the previous component addressed bit
0, this one addresses bit 31).
'previous' - although IMO it'd be unusual to order the component clauses
in non-ascending order (position*System.Storage_Unit + first_bit?), I
don't think the ARM forbids it.
