* m68hc11-tdep.c (gdb_print_insn_m68hc11): Use info->arch 

instead of current_gdbarch.

	* sh64-tdep.c (gdb_print_insn_sh64): Remove.
	(sh64_gdbarch_init): Install print_insn_sh64 directly.
	* sh-tdep.c (gdb_print_insn_sh): Remove.
	(sh_gdbarch_init): Install print_insn_sh directly.

	* mips-tdep.c (gdb_print_insn_mips): Do not check mips_abi
	from current_gdbarch.
	(gdb_print_insn_mips_n32, gdb_print_insn_mips_n64): New functions.
	(mips_gdbarch_init): Install them instead of gdb_print_insn_mips
	depending on mips_abi.
