Sema: Lower scope limit in rdar50025491.swift test and make a gyb variant The -solver-enable-performance-hacks flag has not made a difference here in a while, and it now passes with a lower scope limit. Also the original expression is bespoke but the underlying problem is simpler. Add a new version that doesn't rely on Foundation or IUO syntax sugar, and turn it into a scale-test.
