/// #define OVERRIDE(name, ret, attrs, namespace, typedArgs, namedArgs)
///   Provides information about an overridable function.
///   - name is the name of the function, without any leading swift_ or
///     namespace.
///   - ret is the return type of the function.
///   - attrs is the attributes, if any, applied to the function definition.
///   - namespace is the namespace, if any, the function is in, including a
///     trailing ::
///   - typedArgs is the argument list, including types, surrounded by
///     parentheses
///   - namedArgs is the list of argument names, with no types, surrounded by
///     parentheses
///
/// The entries are organized by group. A user may define OVERRIDE to get all
/// entries, or define one or more of OVERRIDE_METADATALOOKUP, OVERRIDE_CASTING,
/// OVERRIDE_OBJC, OVERRIDE_FOREIGN, OVERRIDE_PROTOCOLCONFORMANCE,
/// and OVERRIDE_KEYPATH to get only those entries.

// NOTE: this file is used to build the definition of OverrideSection in
// Overrides.cpp for the 5.1 compatibility library.  It matches the
// definition of OverrideSection for the 5.1 release and must not be
