Description
The bson_iter_overwrite_int64() function shall overwite the contents of a BSON_TYPE_INT64 element in place.
This may only be done when the underlying bson document allows mutation.
It is a programming error to call this function when iter is not obvserving an element of type BSON_TYPE_INT64.
