This is an alternative for D111137 <https://reviews.llvm.org/D111137>.

If segments are defined in a linker script, placing an orphan section before the found closest-rank section can result in adding it in a previous segment and changing flags of that segment. This happens if the orphan section has a lower sort rank than the found section. To avoid that, the patch forces orphan sections to be moved after the found sections if segments are explicitly defined.
