2bc682e3f3 Do not use left-over space after new space alignment for other spaces. 
Doing so makes the max new space size influence the initial total size
of the heap.

This change reduces the initial memory use of V8 by over 6MB.

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.

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

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.

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

855c654b25 Add LowMemoryNotification to the API on Android platform. 
Android system provides a unique feature that it sends a notification to the
browser in low memory condition, and the browser cleans up cache and frees
resources. Forcing a GC in low memory condition can free DOM objects and also
can shrink the old spaces.

This patch addresses the last comment in

4e03645dc4 Analyze functions for assignment to this properties. 
During parsing functions are analyzed for statements of the form this.x = ...;. These assignments are categorized in two types: simple and non simple. The simple ones are where the right hand side is known to be either a constant or an argument to the function. If a function only contains statements of this type the property names are collected and for the simple assignments the index of the argument or the constant value assigned are stored as well.

When the initial map for a function is created and the function consists of only this type of assignemnts the initial map is created with a descriptor array describing these properties which will be known to always exist in an object created from the function.

The information on this property assignments is not collected during pre-parsing so if compiling using pre-parse data these optimization hints are not available.

Next step will be to use the information collected for the simple assignments to generate constructor code which will create and initialize the object from this information without calling the code for the function.

will have sse3 disabled, but they will not be found when sse3 is

d7449ddebf - Reduced the maximum capacity of a semi space from 8MB to 4MB. 
- Changed the semi space growth policy from doubling to increasing by 50%.
This slows down V8BenchmarkSuite with 1.32% but reduces the memory footprint with 8MB per V8 instance.

395206b1df Add a write() command to d8. This is the same as the print() command, with the 
exception that it does not add a new-line to the end. This half of what is
required to make the Debian Language Shootout code work correctly:

f39651cbcd Land change to notify valgrind when we modify code on x86. This does 
not seem to impact performance and makes it a lot easier for people
embedding V8 to run their application under valgrind.

If we observe a negative performance impact, we will need to revise
this again.
