029e9d52de Handle memory error in print_insn_rx
Nowadays, memory error in rx disassembly is not handled, so if I
start a fresh GDB, and disassemble,

(gdb) set architecture rx
The target architecture is assumed to be rx
(gdb) disassemble 0x0,+4
Dump of assembler code from 0x0 to 0x4:
   0x00000000:	brk
   0x00000001:	brk
   0x00000002:	brk
   0x00000003:	brk

the output is wrong.  This patch adds code to call dis->memory_error_func
on memory error, and longjmp to print_insn_rx.  With this patch applied,

(gdb) set architecture rx
The target architecture is assumed to be rx
(gdb) disassemble 0,+4
Dump of assembler code from 0x0 to 0x4:
   0x00000000:	Cannot access memory at address 0x0
