Don't change compressed input debug section names

Change compressed input debug section name for objdump is very confusing.
But we need to change it for linker so that linker will consider the
input section as a debug section.  This patch delays section rename to
elf_fake_sections for objcopy and avoids it for objdump.

bfd/

	PR binutils/18209
	* bfd.c (bfd): Add is_linker_input.
	* elf.c (convert_debug_to_zdebug): New.
	(convert_zdebug_to_debug): Likewise.
	(_bfd_elf_make_section_from_shdr): Don't convert .debug_* to
	.zdebug_* here.  Use convert_zdebug_to_debug.  Set SEC_ELF_RENAME.
	(_bfd_elf_init_reloc_shdr): Pass a pointer to section name
	instead of a pointer to section.
	(elf_fake_sections): Rename the section name if SEC_ELF_RENAME
	is set.
	* section.c (SEC_ELF_RENAME): New.
	* bfd-in2.h: Regenerated.

binutils/

	PR binutils/18209
	* objcopy.c (setup_section): Copy compress status.

binutils/testsuite/

	PR binutils/18209
	* binutils-all/compress.exp: Replace dw2-3.W with dw2-3gabi.W
	on zlib-gabi output.
	* binutils-all/dw2-1.W: Convert section names to .zdebug_*.
	* binutils-all/dw2-3.W: Likewise.
	* binutils-all/objdump.W: Likewise.
	* binutils-all/dw2-3gabi.W: New file.

ld/

	PR binutils/18209
	* ldfile.c (ldfile_try_open_bfd): Set is_linker_input to 1.
