In `OutputSegment.cpp`, we need to ensure a specific order for certain
sections. The current sorting logic incorrectly prioritizes code
sections over explicitly defined section orders. This is problematic
because the `__objc_stubs` section is both a code section *and* has a
specific ordering requirement. The current logic would incorrectly
prioritize its code section status, causing it to be sorted *before* the
`__stubs` section. This incorrect ordering breaks the branch extension
algorithm, ultimately leading to linker failures due to relocation
errors.
We also modify the `lld/test/MachO/arm64-objc-stubs.s` test to ensure
correct section ordering.
