Add support to the RX toolchain to restrict the use of string instructions.
bfd * elf32-rx.c (describe_flags): Report the settings of the string
insn using bits.
(rx_elf_merge_private_bfd_data): Handle merging of the string insn
using bits.
bin * readelf.c (get_machine_flags): Report the setting of the string
insn using bits.
gas * config/tc-rx.c (enum options): Add OPTION_DISALLOW_STRING_INSNS.
(md_longopts): Add -mno-allow-string-insns.
(md_parse_option): Handle -mno-allow-string-insns.
(md_show_usage): Mention -mno-allow-string-insns.
(rx_note_string_insn_use): New function. Produces an error
message if a string insn is used when it is not allowed.
* config/rx-parse.y (SCMPU): Call rx_note_string_insn_use.
(SMOVU, SMOVB, SMOVF, SUNTIL, SWHILE, RMPA): Likewise.
* config/rx-defs.h (rx_note_string_insn_use): Prototype.
* doc/c-rx.texi: Document -mno-allow-string-insns.
elf * rx.h (E_FLAG_RX_SINSNS_SET): New bit in e_flags field.
(E_FLAG_RX_SINSNS_YES): Likewise.
(E_FLAG_RX_SINSNS_MASK): New define.
