Also, a bug fix: folding a GEP with a leading non-zero index with
its predecessor was incorrect: now it only happens if the predecessor
is pointing to an indexable type (aka SequentialType).

These hash lookups were a major sink of time because they happen so often!
Also, add option to disable scheduling.
