Fix debug section compression so that it is only performed if it would make the section smaller.
PR binutils/18087
gas * doc/as.texinfo: Note that when gas compresses debug sections the
compression is only performed if it makes the section smaller.
* write.c (compress_debug): Do not compress a debug section if
doing so would make it larger.
tests * gas/i386/dw2-compress-1.d: Do not expect the .debug_abbrev or
.debug_info sections to be compressed.
binu * doc/binutils.texi: Note that when objcopy compresses debug
sections the compression is only performed if it makes the section
smaller.
bfd * coffgen.c (make_a_section_from_file): Only prepend a z to a
debug section's name if the section was actually compressed.
* elf.c (_bfd_elf_make_section_from_shdr): Likewise.
* compress.c (bfd_init_section_compress_status): Do not compress
the section if doing so would make it bigger. In such cases leave
the section alone and return COMPRESS_SECTION_NONE.
