Add and move fall-through comments in system-specific code.
This patch fixes -Wimplicit-fallthrough warnings in system-specific code that show up building glibc with -Wextra, by adding fall-through comments, or moving existing such comments to the place required for them to work (immediately before the case label being fallen through). Tested with build-many-glibcs.py. * sysdeps/i386/dl-machine.h (elf_machine_rela): Add fall-through comments. * sysdeps/m68k/m680x0/fpu/s_cexp_template.c (s(__cexp)): Likewise. * sysdeps/m68k/memcopy.h (WORD_COPY_FWD): Likewise. (WORD_COPY_BWD): Likewise. * sysdeps/mach/hurd/ioctl.c (__ioctl): Likewise. * sysdeps/powerpc/powerpc64/dl-machine.h (elf_machine_rela): Likewise. * sysdeps/s390/iso-8859-1_cp037_z900.c (TR_LOOP): Likewise. * sysdeps/mips/dl-machine.h (elf_machine_reloc): Move fall-through comment. * sysdeps/mips/dl-trampoline.c (__dl_runtime_resolve): Likewise.
