/// Designator - A designator in a C99 designated initializer.
///
/// This class is a discriminated union which holds the various
/// different sorts of designators possible. A Designation is an array of
/// these.  An example of a designator are things like this:
///
///      [8] .field [47]        // C99 designation: 3 designators
///      [8 ... 47]  field:     // GNU extensions: 2 designators
///
/// These occur in initializers, e.g.:
///
///      int a[10] = {2, 4, [8]=9, 10};
///
class Designator { … };

/// Designation - Represent a full designation, which is a sequence of
/// designators.  This class is mostly a helper for InitListDesignations.
