Namhyung Kim ec222d7e7c perf hist: Improve srcline sort key performance 
The sort_entry->cmp() will be called for eventy sample data to find a
matching entry.  When it has 'srcline' sort key, that means it needs to
call addr2line or libbfd everytime.

This is not optimal because many samples will have same address and it
just can call addr2line once.  So postpone the actual srcline check to
the sort_entry->collpase() and compare addresses in ->cmp().

Also it needs to add ->init() callback to make sure it has srcline info.
If a sample has a unique data, chances are the entry can be sorted out
by other (previous) keys and callbacks in sort_srcline never called.
