llvm-capstone/lld/MachO/OutputSegment.h
Greg McGary 465204d63a [lld-macho][NFC] define more strings in section_names:: and segment_names::
As preparation for a subsequent diff that implements builtin section renaming, define more `constexpr` strings in namespaces `lld::macho::segment_names` and `lld::macho::section_names`, and use them to replace string literals.
