- 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.

This will allow us (later) to make nice descriptions of the state of
an isolate, e.g. "isolate 7112 is paused due to breakpoint 2" or
"isolate 7112 is paused due to interrupt" or "isolate 7112 is
running".
Use a new Pause() function to call the event handler during a pause.
It does some shared checking, setup, teardown.
Minor change in isolate interrupt handling - before we were not
setting 'in_event_handler_' in this case. Now we set 'pause_event_'
here, which will guard against recursive pauses in this case.
Reviewer: not sure what I think about all the names I used here.
"pause_event_" is very similar to PausedEvent but means something
different, as it includes pauses, interrupts, and (maybe) exceptions.
Dunno.
