 * \brief Apply MergeIfStmt transformation to a PrimFunc

 * Example:
 *   if (cond) { stmt1 }
 *   if (cond) { stmt2 }
 *   if (cond) { stmt3 }
 *
 * Becomes:
 *   if (cond) {
 *     stmt1
 *     stmt2
 *     stmt3
 *   }
 *
 * \param f The PrimFunc to transform
 * \return Transformed PrimFunc with merged if statements
