perf annotate-data: Parse 'lock' prefix from llvm-objdump

For the performance reason, I prefer llvm-objdump over GNU's.  But I
found that llvm-objdump puts x86 lock prefix in a separate line like
below.

  ffffffff81000695: f0                    lock
  ffffffff81000696: ff 83 54 0b 00 00     incl    2900(%rbx)

This should be parsed properly, but I just changed to find the insn
with next offset for now.

This improves the statistics as it can process more instructions.

  Annotate data type stats:
  total 294, ok 144 (49.0%), bad 150 (51.0%)
  -----------------------------------------------------------
          30 : no_sym
          35 : no_mem_ops
          71 : no_var
           6 : no_typeinfo
           8 : bad_offset
