[disasm] Make jump target printing perf friendly

[disasm] Make jump target printing perf friendly

Makes disassembly jump target printing look more like the output of
objdump, for compatibility with perf's jump arrows. This includes
swapping the order of address and offset, and making the offset and line
numbers hex.

As a drive-by, print comment lines in objdump-v8 so that they can be
shown/hidden as "source" lines by perf.

Hi Yang,
Continuing my previous CL trying to make things more perf friendly, here's one
that makes the jump arrows work. WDYT?

Ross: fyi
