perf/core inline improvements:

From Milian's cover letter: (Milian Wolff)
 
 This series of patches completely reworks the way inline frames are
 handled.  Instead of querying for the inline nodes on-demand in the
 individual tools, we now create proper callchain nodes for inlined
 frames. The advantages this approach brings are numerous:
 
 - Less duplicated code in the individual browser
 
 - Aggregated cost for inlined frames for the --children top-down list
 
 - Various bug fixes that arose from querying for a srcline/symbol based on
   the IP of a sample, which will always point to the last inlined frame
   instead of the corresponding non-inlined frame
 
 - Overall much better support for visualizing cost for heavily-inlined C++
   code, which simply was confusing and unreliably before
 
 - srcline honors the global setting as to whether full paths or basenames
   should be shown
 
 - Caches for inlined frames and srcline information, which allow us to
   enable inline frame handling by default
