Frederic Weisbecker 301406b9c6 perf annotate: Print the filename:line for annotated colored lines
When we have a colored line in perf annotate, ie a middle/high
overhead one, it's sometimes useful to get the matching line
and filename from the source file, especially this path prepares
to another subsequent one which will print a sorted summary of
midle/high overhead lines in the beginning of the output.

Filename:Lines have the same color than the concerned ip lines.

It can be slow because it relies on addr2line. We could also
use objdump with -l but that implies we would have to bufferize
objdump output and parse it to filter the relevant lines since
we want to print a sorted summary in the beginning.
