A distinction that doesn't _usually_ matter is that the MachO::SymbolKind is really a mapping of entries in TBD files not symbols. To better understand this, rename the enum so it represents an encoding mapped to TBDs as opposed to symbols alone. For example, it can be a bit confusing that "GlobalSymbol" is a enum value when all of those values can represent a GlobalSymbol.
