48a99323a4 We've got complains that sending afterCompile events to debug message handler may have considerable impact on the profiler when inspected script does lots of 'eval's. The proposed solution is to request source of the compiled script lazily instead of sending it in afterCompile event.

17362b27ea Changed RegExp parser to use a recursive data structure instead of stack-based recursion. 
Shouldn't run out of stack space while parsing deeply nested regexps.

25405ddd9c Handle JavaScript accessors on the global object. 
With the new representation of the global object adding JavaScript accessors for a property after global inline caches was created for that property did not work property as the inline caches did not take the JavaScript accessor information (fixed array with two elements) that could be present in a global object property cell into account.

This is now fixed by changing the map for a global object when a JavaScript accessor is defined on it.

8318f5e5f1 Reimplement profiler sampler on Mac OS X to get it working under Chromium. 
Previous implementation of sampler for OS X was copied from the Linux one. But BSD (OS X) and Linux has a very important difference in signal handling. LinuxThreads doesn't support the notion of process-directed signals. So, the SIGPROF signal was directed to the thread that installed the handler---the V8 thread. But on BSD, signal handling is implemented according to POSIX spec, where process-directed signal is to be handled by an arbitrary selected thread. By a coincidence, in V8's sample shell and in Chromium's test shell, V8's thread was picked almost every time, so sampling seemed working. But not in case of Chromium.

So, I've changed the implementation of profiler sampler to use the same scheme as on Windows---a dedicated thread with high priority is used to periodically pause and sample V8's thread.
