Make "set disassemble-next-line on" can work with DUMMY_FRAME, SIGTRAMP_FRAME and ARCH_FRAME

Browse source 
When GDB debug DUMMY_FRAME, SIGTRAMP_FRAME and ARCH_FRAME, even if
"set disassemble-next-line on", it will not output the asm code:
(gdb) set disassemble-next-line on
(gdb) si
<signal handler called>
(gdb)
<signal handler called>
(gdb)
<signal handler called>

So make this patch make they can work together, it will become:
(gdb) si
<signal handler called>
=> 0xffffffff816bfb09 <int_with_check+0>:	65 48 8b 0c 25 c8 c7 00 00	mov    %gs:0xc7c8,%rcx
(gdb)
<signal handler called>
=> 0xffffffff816bfb12 <int_with_check+9>:	48 81 e9 d8 1f 00 00	sub    $0x1fd8,%rcx
(gdb)
<signal handler called>
=> 0xffffffff816bfb19 <int_with_check+16>:	8b 51 10	mov    0x10(%rcx),%edx
