Issue Description:

Both fluent and SwiftLint projects seem to be failing for an issue in SILGen. Stack traces look similar starting with this:

7 swift 0x00000001044440aa (anonymous namespace)::PatternMatchEmission::emitSpecializedDispatch((anonymous namespace)::ClauseMatrix&, llvm::ArrayRef<swift::Lowering::ConsumableManagedValue>, unsigned int&, unsigned int, std::__1::function<void (swift::SILLocation)> const&) + 12410
