[DFAJumpThreading] make update order deterministic
We tracked down some non-determinism in compilation output to the
DFAJumpThreading pass. These changes fixed our issue:
* Make the DefMap type a MapVector to make its iteration order depend on
insertion order.
* Sort the values to be inserted into NewDefs by instruction order to
make the insertion order deterministic. Since these values come from
iterating over a ValueMap, which doesn't have deterministic iteration
order, I couldn't fix this at its source.
