For i64 pair tuples in _makeConcrete, add makeWideIntExpression with
VeryImportant weight (requiring Multivalue as well as WideArithmetic)
alongside makeTupleMake instead of replacing it half the time with
default weight. This increases generation of unextracted (i64, i64)
wide arithmetic expressions by ~4.2x.
