GNU ld allows sections after a non-SHF_ALLOC section to be covered by PT_LOAD (PR37607) and assigns addresses to non-SHF_ALLOC output sections (similar to SHF_ALLOC NOBITS sections. The location counter is not advanced). This patch tries to fix PR37607 (remove a special case in `Writer<ELFT>::createPhdrs`). To make the created PT_LOAD meaningful, we cannot reset dot to 0 for a middle non-SHF_ALLOC output section. This results in removal of two special cases in LinkerScript::assignOffsets. Non-SHF_ALLOC non-orphan sections can have non-zero addresses like in GNU ld. The zero address rule for non-SHF_ALLOC sections is weakened to apply to orphan only. This results in a special case in createSection and findOrphanPos, respectively. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D85100
