Dmprof may not support content shell as the modification here, 
but when I just try to use dmprof in content shell and the result is that I
don't have the same problem (currently I still not merge the bug).
At last, I  find out the reason is that my path have the key word chrome:
/home/view/dtv_view/hewensheng/chrome37/src/out_type_nop/Release/content_shell
So I think this is not accurate for the matching rule for the pathname in
/proc/[pid]/maps. Better to add '$' in the RE here, I think.

Please take a look in prepare_symbol_info.py. It now accepts any file if the
file is executable. content_shell is used by this rule.
