Qunxin Liu af1e605be2 [instancer] bug fix

empty.

Behdad Esfahbod 64fa5cd482 [GPOS] Fix assert fail introduced recently
Was introduced in 8708b9e081.

If these lookups are recursed to from (Chain)Context out-of-order,
it was possible that last_base > buffer->idx, in which case we
were attaching marks to a base after them... and an assertion
was failing fortunately.
