Hi Ingo,

Here are bugfixes and some enhances of x86-insn decoder and perf-probe.
 - x86 insn decoder supports AVX and FMA.
 - perf-probe syntax change.
 - perf-probe supports function-relative line number.
 - minor bugfixes.

New perf-probe syntax is below:

  perf probe 'PROBE'

 or 

  perf probe --add 'PROBE'

 where, PROBE is

  <source>:<line-number>

 or

  <function>[:<rel-lineno>|+<byte-offset>|%return][@<source>]

 e.g.

  perf probe 'schedule:10@kernel/sched.c'

  puts a probe at 10th line from entry line of schedule() function
  in kernel/sched.c." and

  perf probe 'vmalloc%return'

  puts a return probe at the returning of vmalloc.

TODO:
 - Support --line option to show which lines user can probe.
 - Support lazy string matching.

Thank you,

---
