bcff52624d Cleaned up some debugger stuff on ia32 and x64. 
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.

Added some missing ENABLE_DEBUGGER_SUPPORT #ifdef/#endif.

f4d3ff1ac3 Find the correct function for script break points 
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.

0411b14ffa Heap profiler: account primitive string objects as being constructed using 'String'. 
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.

bbc3c97c2c 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

ae062d5df1 Added new scope type ScopeIterator::ScopeTypeCatch for with generated from catch blocks. 
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.

def729b6ad Change to limit the amount of space we waste due to fragmentation 
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.

ab54e95377 Support stepping in functions called using CallFunction stub. When Debug::PrepareStep is called to prepare 'step in' and current code target is CallFunction stub, the debugger will find function being called on the expression stack and flood it with one shot breakpoints. 
BreakLocationIterator changed to treat 'debugger;' statements as a possible break location. Since 'debugger;' statement should always invoke debugger it is hanled in a special way.
