address, especially if debugging is enabled, so we must
take care to adjust all the labels at this address in this
fragment. To save time we search from the end of the symbol
list, backwards, since the symbols we are interested in are
almost certainly the ones that were most recently added.
Also to save time we stop searching once we have seen at least
one matching label, and we encounter a label that is no longer
in the target fragment. Note, this search is guaranteed to
find at least one match when sym == label, so no special case
code is necessary. */
