Patch to make ivopts take autoincrement addressing modes into account
Ivopts take autoincrement addressing modes into account with this patch (in a
fairly simplistic form, sufficient to improve the code for the testcases in
this PR). However, I do not have access to any architecture where I could test
it (I somewhat suspect it might cause performance regressions -- using
autoincrement addressing modes is not necessarily always profitable).
