Jake Ehrlich f69705a3db [llvm-objcopy] Fix handling of zero-size segments in llvm-objcopy ... Some ELF files produced by lld may have zero-size segment placeholders as shown below. Since GNU_STACK Offset is 0, the current code makes it the lowest used offset, and relocates all the segments over the ELF header. The resulting binary is total garbage. This change fixes how llvm-objcopy handles PT_PHDR properlly by treating ELF headers and the program header table as segments to allow the layout algorithm decide where those should go.
