Summary
Fix overlay table entries after executable sections are sorted by ROM address.
The table stores original
SectionTableEntry::indexvalues, butinit_overlays()sortscode_sectionsin place. After sorting, those values no longer necessarily match positions incode_sections, so overlay lookups can resolve the wrong section.This builds an original-index to sorted-index map and remaps the overlay table after sorting.
