finalizeAddressDependentContent assigns addresses, then --randomize-section-padding and CFI jump table relaxation (--branch-to-branch, implied by -O2) move input sections, so the first fixed-point iteration computes address-dependent content from stale addresses. Since #179089, EhFrameHeader::updateAllocSize caches the .eh_frame_hdr search table; if no iteration changes anything, the loop exits and the table keys no longer match the FDEs' initial_location. Neither transform reads addresses, so run them before the first assignAddresses. SHF_LINK_ORDER sections are now sorted by the relaxed layout as well. LLM-aided. Partially fix #226166 (cherry picked from commit 115554f90f920fc000234c2c247b8318d4e7d2d8)
