Use correct symbol for minimum int64 value
The old code used SEQ_MINVALUE to get the smallest int64 value. Thiswas done as a convenience to avoid having to deal with INT64_IS_BUSTED,but that is obsolete now. Also, it is incorrect because the smallestint64 value is actually SEQ_MINVALUE-1. Fix by writing out the constantthe long way, as it is done elsewhere in the code.
