Add support for G13 and G14 flag bits in RL78 ELF binaries.
inc * rl78.h (E_FLAG_RL78_G10): Redefine.
(E_FLAG_RL78_CPU_MASK, E_FLAG_RL78_ANY_CPU, E_FLAG_RL78_G13
E_FLAG_RL78_G14): New flags.
bin * readelf.c (get_machine_flags): Decode RL78's G13 and G14 flags.
gas * config/tc-rl78.c (enum options): Add G13 and G14.
(md_longopts): Add -mg13 and -mg14.
(md_parse_option): Handle -mg13 and -mg14.
(md_show_usage): List -mg13 and -mg14.
* doc/c-rl78.texi: Add description of -mg13 and -mg14 options.
bfd * elf32-rl78.c (rl78_cpu_name): New function. Prints the name of
the RL78 core based upon the flags.
(rl78_elf_merge_private_bfd_data): Handle merging of G13 and G14
flags.
(rl78_elf_print_private_bfd_data): Use rl78_cpu_name.
(elf32_rl78_machine): Always return bfd_mach_rl78.
