- Identify a source breakpoint by a script and a token position rather than a function object. - When a new breakpoint is set, iterate over all compiled functions to see whether code breakpoints must be set. This change fixes issues with functions that get compiled several times, for example as implicit closures or a copies of mixin functions or local closures of mixing functions. We did not detect all duplicates of functions. Eliminated recently introduced const modifiers in SourceBreakpoint class. They tend to be in the way because several accessor methods of SourceBreakpoint compute data lazily and modify the object as a side effect.
