* mips.h: Assign 'm'/'M' codes to MIPS16e save/restore
instructions. Define MIPS16_ALL_ARGS and MIPS16_ALL_STATICS for
save/restore encoding of the args field.
* mips16-opc.c: Add MIPS16e save/restore opcodes.
* mips-dis.c (print_mips16_insn_arg): Handle printing of 'm'/'M'
codes for save/restore.
* config/tc-mips.c (mips16_ip): Add handling of 'm' and 'M' codes
for the MIPS16e save/restore instructions.
* gas/mips/mips.exp: Run new save/restore tests.
* gas/testsuite/gas/mips/mips16e-save.s: New test for generating
different styles of save/restore instructions.
* gas/testsuite/gas/mips/mips16e-save.d: New.
