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.

369214c159 Use a root array register for constant loads and stack guards on x64. 
This only wins us around 1% in performance, but it makes the code more
compact.  We don't currently have a way to represent in the virtual
frame that a slot contains a value from the root array.  Adding this
would probably make the code more compact.

717394492d Generate specialized constructor code for constructing simple objects. 
For objects which only have simple assignments of the form this.x = ...; a
specialized constructor stub is now generated. This generated code allocates the
object and fills in the initial properties directly. If this fails for some
reason code continues in the generic constructor stub which in turn might pass
control to the runtime system.

Added counter to see how many objects are constructed using a specialized stub.

The specialized stub is only implemented for ia32 architecture in this change.
For x64 and ARM the generic construct stub is used.

This is change is identical to http://codereview.chromium.org/174392 (committed in r2753 and reverted in r2754) except that a few parts have already been committed from http://codereview.chromium.org/173469 (committed in r2762).

When copying a map always set the descriptor array to describe the pre-allocated properties, even when descriptors are to be dropped.

Added a test which otherwise failed with an assert on ARM in debug mode. The reason for it only surfasing on ARM is that the NewObject runtime function is always used for allocating new JSObjects on ARM.

b8a73f0650 Fix uninitialized members. 
Make sure that the DummyScope top level scope used for pre-parsing have all members initialized. The type of this scope is set to global scope as it is a top level scope. Also ensure that the "naked" Scope constructor can only be used by sub-classes of Scope.

The bug of missing initiaalization of members in the DummyScope was found by Valgrind.

5e0a513e29 Temporarily revert the reduction of semispace sizes and the growth 
policy change.

I will put the changes back one at a time so we can see the effect of
them in isolation.  Also, there is a bug in the growth policy change
that I will fix before putting it back again.
