/// Interface for representing a type system.
///
/// Implemented by language plugins to define the type system for a given
/// language.
///
/// This interface extensively used opaque pointers to prevent that generic
/// LLDB code has dependencies on language plugins. The type and semantics of
/// these opaque pointers are defined by the TypeSystem implementation inside
/// the respective language plugin. Opaque pointers from one TypeSystem
/// instance should never be passed to a different TypeSystem instance (even
/// when the language plugin for both TypeSystem instances is the same).
///
/// Most of the functions in this class should not be called directly but only
/// called by their respective counterparts in CompilerType, CompilerDecl and
/// CompilerDeclContext.
