* 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.
