This is trying to make it clearer when vectors are being indexed with `CheckIRId`. The only one that I still kind of want to change is the `SmallVector<std::unique_ptr<CompilationUnit>>`, but because it's a `unique_ptr` that's a little more complex. I may not bother. Note, some of the changes around nuanced `SmallVector` interactions were based on trying to copy the way `SmallVector` itself takes arguments, like with range passing.
