Florian Hahn a4ffa3accf [LegacyPM] Use MapVector for OnTheFlyPassManagers. ...

Currently the iteration order of OnTheFlyManagers is not deterministic
between executions, which means some of test/Other/opt-*-pipeline.ll
tests fail non-deterministically if an additional on-the-fly manager is
added, as in D45330.

By using MapVector, we always iterate in the insertion order. As we are
not removing elements, there shouldn't be a performance hit, except that
we store an additional vector with the keys.
