Handle ELF compressed header alignment correctly by setting up the section alignment correctly for the Elf32_Chdr or Elf64_Chdr type and respect the ch_addralign field when decompressing the section data.
PR binutils/23919
binutils* readelf.c (dump_sections_as_strings): Remove bogus addralign check.
(dump_sections_as_bytes): Likewise.
(load_specific_debug_sections): Likewise.
* testsuite/binutils-all/dw2-3.rS: Adjust alignment.
* testsuite/binutils-all/dw2-3.rt: Likewise.
bfd * bfd.c (bfd_update_compression_header): Explicitly set alignment.
(bfd_check_compression_header): Add uncompressed_alignment_power
argument. Check ch_addralign is a power of 2.
* bfd-in2.h: Regenerated.
* compress.c (bfd_compress_section_contents): Get and set
orig_uncompressed_alignment_pow if section is decompressed.
(bfd_is_section_compressed_with_header): Add and get
uncompressed_align_pow_p argument.
(bfd_is_section_compressed): Add uncompressed_align_power argument
to bfd_is_section_compressed_with_header call.
(bfd_init_section_decompress_status): Get and set
uncompressed_alignment_power.
* elf.c (_bfd_elf_make_section_from_shdr): Add
uncompressed_align_power argument to
bfd_is_section_compressed_with_header call.
