The reader creates mergeable strings for sections that have the flag SHF_MERGE|SHF_STRINGS set, Lets delay string merging until the output fie is being written to disk.

The time will also be saved because the reader may try to atomize a section
that is has been garbage collected containing strings very early when garbage
collection is enabled.
