Optimizer: force progression through final passes when hitting limit

Browse Source 
We have a number of bug reports about things not working properly when
the optimizer is running out of passes.  I suspect the reason is
simply that we don't properly execute the final passes (pass0 = 1, 2)
when hitting the limit.  Make sure we advance pass0 the last few
times.
