Arnaldo Carvalho de Melo 51a0d455b5 perf annotate browser: Add visual cues on jump lines
Using up/down arrows just before the instruction, replacing the actual chars
with approximations to avoid mail encoding snafus:

    0.00 | 79:  cmp    %r8w,0x4(%rax)

    0.00 |    ^ jne    60
    0.00 |      leaveq
    0.00 |      retq

Next low hanging fruit is to use left arrow for retqs, then work on clearling
marking loops.
