94879a93b0 Add a script cache to the debugger
When loaded scripts are requested this cache is filled with all the script objects in the heap. Hereafter its content is kept in sync with the active scripts in the heap through the notifications of new scripts compiled and by using weak handles to get notified when a script is collected.

Through the tracking of collected scripts the debugger event OnScriptCollected have been added to notify a debugger that a script previously returned through the scripts command is no longer in use.

Make the ComputeIntegerHash globally available.

Moved clearing of the mirror cache to when debugger is really left. Previously recursive invocations of the debugger cause the mirror cache to be cleared causing handles to become either stale or reference other objects.

ef85ba46b0 First round of size reduction for JumpTargets. Reduce their size by
two words: there is no reason to keep a pointer to the current code
generator and macro assembler in the JumpTarget.

6a350c86bf If 'compactFormat' argument is passed in the request the response won't include referenced mirrors in the refs section instead each protocol reference object will contain some details necessary for displaying the referenced object in the graphical debugger when the object is not expanded. That allows to request full information lazily when the object is expanded.

f4778b007f Reduce the memory used by frame elements from two words to one by
