perf annotate: Introduce scnprintf ins_ops method
And implement the jump one, where if the operands string is not passed,
a compact form that uses just the target address is used.
Right now this is toggled via the 'o' option in the annotate browser,
switching from:
0.00 : ffffffff811661e8: je ffffffff81166204 <mem_cgroup_count_vm_event+0x44>
0.00 : ffffffff811661ea: cmp $0xb,%esi
0.00 : ffffffff811661ed: je ffffffff811661f8 <mem_cgroup_count_vm_event+0x38>
To:
0.00 : 28: je 44
0.00 : 2a: cmp $0xb,%esi
0.00 : 2d: je 38
