  @param {Element} oIfElement
  the <template:if> XML DOM element
  @param {sap.ui.core.util._with} oWithControl
  the "with" control
  @returns {sap.ui.base.SyncPromise}
  A sync promise which resolves with <code>undefined</code> as soon as the
  <template:if> instruction has been fully processed, or is rejected with a
  corresponding error if visiting child nodes fails.
