The first step, which is relatively easy and should be done anyway,
is to use ASET (a, i, v) instead of AREF (a, i) = v when setting vectors,
as that's how ASET and AREF are supposed to be used.
I did that as trunk bzr 109381.  I created a new function aref_addr (a, i)
to substitute for "& AREF (a, i)" -- presumably the (rare)
calls to aref_addr will need special attention if write barriers
are implemented.
