Insert the specified `numElements` in the range `[first .. last)]` at the specified `position`, by moving the elements in the range `[position .. fromEnd)]` forward by `numElements` position. Pass the specified `allocator` to the copy constructor if appropriate. Load into the specified `toEnd` an iterator to the end of the data after insertion (i.e., `fromEnd + numElements`). The behavior is undefined unless `fromEnd + numElements` is a valid iterator (i.e., the block pointer array holds enough room after the `fromEnd` position to insert `numElements`).
