Make RL78 disassembler and simulator respect ISA for mul/div

[gas]
	* config/rl78-defs.h (rl78_isa_g10): New.
	(rl78_isa_g13): New.
	(rl78_isa_g14): New.
	* config/rl78-parse.y (ISA_G10): New.
	(ISA_G13): New.
	(ISA_G14): New.
	(MULHU, MULH, MULU, DIVHU, DIVWU, MACHU, MACH): Use them.
	* config/tc-rl78.c (rl78_isa_g10): New.
	(rl78_isa_g13): New.
	(rl78_isa_g14): New.

[gdb]
	* rl78-tdep.c (rl78_analyze_prologue): Pass RL78_ISA_DEFAULT to
	rl78_decode_opcode

[include]
	* dis-asm.h (print_insn_rl78_g10): New.
	(print_insn_rl78_g13): New.
	(print_insn_rl78_g14): New.
	(rl78_get_disassembler): New.
	* opcode/rl78.h (RL78_Dis_Isa): New.
	(rl78_decode_opcode): Add ISA parameter.

[opcodes]
	* disassemble.c (disassembler): Choose suitable disassembler based
	on E_ABI.
	* rl78-decode.opc (rl78_decode_opcode): Take ISA parameter.  Use
	it to decode mul/div insns.
	* rl78-decode.c: Regenerate.
	* rl78-dis.c (print_insn_rl78): Rename to...
	(print_insn_rl78_common): ...this, take ISA parameter.
	(print_insn_rl78): New.
	(print_insn_rl78_g10): New.
	(print_insn_rl78_g13): New.
	(print_insn_rl78_g14): New.
	(rl78_get_disassembler): New.

[sim]
	* rl78/cpu.c (g14_multiply): New.
	* rl78/cpu.h (g14_multiply): New.
	* rl78/load.c (rl78_load): Decode ISA completely.
	* rl78/main.c (main): Expand -M to include other ISAs.
	* rl78/rl78.c (decode_opcode): Decode based on ISA.
	* rl78/trace.c (rl78_disasm_fn): New.
	(sim_disasm_init): Reset it.
	(sim_disasm_one): Get correct disassembler for ISA.
