/// <remarks>
/// There's generally two ways to display a label:
/// (1) When displaying labels on-screen, we get a label with the uniquification tag,
/// and we want to show the non-unique label prefix ('@' or ':') and annotation.
/// (2) When generating assembly source, we get a remapped label with no uniquification
/// tag, and we don't want to show the prefix or annotation.
/// For case #2, there's no reason to call here. (We're currently doing so because
/// remapping isn't happening yet, but that should change soon. When that happens, we
/// should be able to eliminate the showNonUnique arg.)
