In my experience, breaks and continues disappear when converting AST to IR. But
maybe it's useful to keep around if you are targeting GLSL.

Breaks and continues would normally turn into gotos, but as you indicate I need
to be able to target a language that does not have goto.

+    BreakStatement(Position position)
+    : INHERITED(position, kBreak_Kind) {}
+
+    std::string description() const override {
+        return "break;";
+    }
+
+    typedef Statement INHERITED;
+};
+
+} // namespace
+
+#endif
