Add fall-through comments.
This patch adds fall-through comments in some cases where -Wextra produces implicit-fallthrough warnings. The patch is non-exhaustive. Apart from architecture-specific code for non-x86_64 architectures, it does not change sunrpc/xdr.c (legacy code, probably should have such changes, but left to be dealt with separately), or places that already had comments about the fall-through but not matching the form expected by -Wimplicit-fallthrough=3 (the default level with -Wextra; my inclination is to adjust those comments to match rather than downgrading to -Wimplicit-fallthrough=1 to allow any comment), or one place where I thought the implicit fallthrough was not correct and so should be handled separately as a bug fix. I think the key thing to consider in review of this patch is whether the fall-through is indeed intended and correct in each place where such a comment is added. Tested for x86_64. * elf/dl-exception.c (_dl_exception_create_format): Add fall-through comments. * elf/ldconfig.c (parse_conf_include): Likewise. * elf/rtld.c (print_statistics): Likewise. * locale/programs/charmap.c (parse_charmap): Likewise. * misc/mntent_r.c (__getmntent_r): Likewise. * posix/wordexp.c (parse_arith): Likewise. (parse_backtick): Likewise. * resolv/ns_ttl.c (ns_parse_ttl): Likewise. * sysdeps/x86/cpu-features.c (init_cpu_features): Likewise. * sysdeps/x86_64/dl-machine.h (elf_machine_rela): Likewise.
