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
