Continuing work from #18344, be more conservative about when we load SwiftOnoneSupport. Specifically, -emit-silgen and -emit-sibgen, despite not going through the SIL Optimizer, may silently introduce dependencies on SwiftOnoneSupport. Because we want to support the ability to posthumously compile SILGen and SIBGen'd files with these implicit dependencies, and because SIL is not yet capable of expressing the dependency itself, we must always assume we need to load SwiftOnoneSupport.
