Represents a C99 designated initializer expression.
A designated initializer expression (C99 6.7.8) contains one or more designators (which can be field designators, array designators, or GNU array-range designators) followed by an expression that initializes the field or element(s) that the designators refer to. For example, given:
The InitListExpr contains three DesignatedInitExprs, the first of which covers [2].y=1.0. This DesignatedInitExpr will have two designators, one array designator for [2] followed by one field designator for .y. The initialization expression will be 1.0.
