[Core] Fix a bug in how source file names were written in .istats files.

 - KCachegrind appears to expect the first function name to be preceeded by the
   name of the file it appears in. Otherwise, it will end up creating two
   different records for the function, one of which has no file name and won't
   have any statistics.
