Subject: [PATCH 0/4] perf annotate: Fixes for line numbers and Introduce source_code

Hi, :)

Currently perf-annotate have several problems.

  - Wrong line numbers on perf-annotate (both stdio and TUI)
  - Wrong sum of overhead(percent) matching source lines 
  - It's so confusing that the output is mixed with
    both source code and assembly code. (related to depending on 'objdump -S') 

So fix them regarding wrong line numbers
and Introduce new source_code collecting actual code,
not depending on 'objdump -S'.

In near future, I have a plan for new reable annotate view
base on source code (per function(sym)) using the 'struct source_code'. :)

I'd appreciate some feedback.

(Current v1 don't consider improvement of performance of annotate
and don't make code of annotate more compact so I'll consider them in v2) 

Thanks,
Taeung

  perf annotate: Change the method counting line numbers
  perf annotate: Introduce source_code to collect actual code
