fixes #156417 When the relocation section is placed before the relocated section and the relocated section is not defined in the linker script, an error will occur during the linking process. **Issue Cause:** In a.ro, `.rela.text` precedes its relocated `InputSection` `.text`. `addOrphanSections` doesn't handle this scenario. When it processes `.rela.text`, in the called `getOutputSectionName`, `rel->getOutputSection()` is nullptr (input `.text` doesn't yet have a parent output section), leading to an assertion failure. **Solution:** For --emit-relocs and -r, ensure the output section for `.text.foo` is created before the output section for `.rela.text.foo`. --------- Co-authored-by: Fangrui Song <i@maskray.me>
