Fixes PR50637. Downstream bug: https://crbug.com/1218958 Currently, we split __cstring along symbol boundaries with .subsections_via_symbols when not deduplicating, and along null bytes when deduplicating. This change splits along null bytes unconditionally, and preserves original alignment in the non- deduplicated case. Removing subsections-section-relocs.s because with this change, __cstring is never reordered based on the order file. Differential Revision: https://reviews.llvm.org/D104919
