Arnaldo Carvalho de Melo e4cc91b802 perf annotate: Support jumping from one function to another
For instance:

  entry_SYSCALL_64  /lib/modules/4.16.0-rc5-00086-gdf09348f78dc/build/vmlinux
    5.50 │     → callq  do_syscall_64
   14.56 │       mov    0x58(%rsp),%rcx
    7.44 │       mov    0x80(%rsp),%r11
    0.32 │       cmp    %rcx,%r11
         │     → jne    swapgs_restore_regs_and_return_to_usermode
    0.32 │       shl    $0x10,%rcx
    0.32 │       sar    $0x10,%rcx
    3.24 │       cmp    %rcx,%r11
         │     → jne    swapgs_restore_regs_and_return_to_usermode
    2.27 │       cmpq   $0x33,0x88(%rsp)
    1.29 │     → jne    swapgs_restore_regs_and_return_to_usermode
         │       mov    0x30(%rsp),%r11
    8.74 │       cmp    %r11,0x90(%rsp)
         │     → jne    swapgs_restore_regs_and_return_to_usermode
    0.32 │       test   $0x10100,%r11
         │     → jne    swapgs_restore_regs_and_return_to_usermode
    0.32 │       cmpq   $0x2b,0xa0(%rsp)
    0.65 │     → jne    swapgs_restore_regs_and_return_to_usermode

It'll behave just like a "call" instruction, i.e. press enter or right
arrow over one such line and the browser will navigate to the annotated
disassembly of that function, which when exited, via left arrow or esc,
will come back to the calling function.

Now to support jump to an offset on a different function...
