The SCons build now has the options profilingsupport and debuggersupport for controlling the setting of the defines ENABLE_LOGGIGN_AND_PROFILING and ENABLE_DEBUGGER_SUPPORT. By default both are set to true.

The changes to the XCode project have not been tested.

If there is a local cpplint.py in the tools directory use this instead of any cpplint in the path. This makes it possible to run presubmit checks on Windows by downloading cpplint.py from http://code.google.com/p/google-styleguide/.

Use the code patcher for the patching of the JS return sequence used by the debugger.

Added explicit instruction cache flushing in a code patching section which did not have it for completeness, even though it is not required on Intel processors.

Got rid of the debug break on return entry code which did not add anything. It just jumped directly to the debug break on return code.

Removed the CodePatcher class on x64 as it was not implemented.

Added instruction cache flush to where the return sequence was patched on x64.

The algorithm for finding the inner-most function containing a script break point was not correct when the script only contained one function. In that case the script function and not the actual function in the script could be returned depending on the order of the objects in the heap.

Also:
- move constructor name getter near similar class name getter method;
- if the constructor is not present, use 'Object', as for class name, this eliminates a special case.

Support stepping out for recursive functions.Simply flooding JS function from the calling stack frame with one shot breakpoints is not enough to support step out action in all cases since the function on top of the stack may be turn recursive and we may end up flooding itself. To overcome this a pointer to the stack frame where the debugger should be invoked after stepping out is strored in the debugger.Chromium bug:http://code.google.com/p/chromium/issues/detail?id=17967

Removed a false assertion in ScopeIterator that assumed context extension to never be a JSContextExtensionObject.

The context extension object in a 'with' context is JSContextExtensionObject iff the 'with' statement is generated from a catch block in order to extend its local scope with a variable holding exception object. This is how we differentiate 'catch' scope from 'with' scope.

in old space. Before this change we would compute the fragmentation 
limit before the GC, but that means that we take all the garbage 
into account - and consequently we almost never hit the limit (because 
we have a lot of garbage).

This change changes the policy to compact on the *next* GC if we
determine that we have too much fragmentation after doing a GC.
We'll do a GC if we've wasted more than 1MB and more than 15% of
the old space size.

This can be further improved by computing whether or not to compact
during the marking phase.
