0fc72f2b4e Serendipitously arrange the tags so that String.length() becomes a branch-free 
operation.  I have another version of this change that does not remove the
special inline caches for difference sized strings.  The other version is ever
so slightly faster, but the nice thing about this version is that it removes
253 lines of code.

6941a4f389 Collects unused maps that are only kept alive by map transitions. 
If a map has descendents in the map transition tree that are alive,
it is kept.  Only maps such that they and all their descendants
have no live objects are collected.  This happens in mark-sweep and
mark-compact garbage collections.

that the exception stored in the TryCatch is not cleared as that was the
cause of the regression.

- Move printing of the command to after printing std{err,out} in the
  compact progress indicators in the test framework.

been bypassed by code in a finally block.

42ef2c3d77 Split window support from V8. 
Here is a description of the background and design of split window in Chrome and V8:
https://docs.google.com/a/google.com/Doc?id=chhjkpg_47fwddxbfr

This change list splits the window object into two parts: 1) an inner window object used as the global object of contexts; 2) an outer window object exposed to JavaScript and accessible by the name 'window'. Firefox did it awhile ago, here are some discussions: https://wiki.mozilla.org/Gecko:SplitWindow. One additional benefit of splitting window in Chrome is that accessing global variables don't need security checks anymore, it can improve applications that use many global variables.

V8 support of split window:
  There are a small number of changes on V8 api to support split window:
Security context is removed from V8, so does related API functions;
A global object can be detached from its context and reused by a new context;
Access checks on an object template can be turned on/off by default;
An object can turn on its access checks later;

  V8 has a new object type, ApiGlobalObject, which is the outer window object type. The existing JSGlobalObject becomes the inner window object type. Security checks are moved from JSGlobalObject to ApiGlobalObject. ApiGlobalObject is the one exposed to JavaScript, it is accessible through Context::Global(). ApiGlobalObject's prototype is set to JSGlobalObject so that property lookups are forwarded to JSGlobalObject. ApiGlobalObject forwards all other property access requests to JSGlobalObject, such as SetProperty, DeleteProperty, etc.

  Security token is moved to a global context, and ApiGlobalObject has a reference to its global context. JSGlobalObject has a reference to its global context as well. When accessing properties on a global object in JavaScript, the domain security check is performed by comparing the security token of the lexical context (Top::global_context()) to the token of global object's context. The check is only needed when the receiver is a window object, such as 'window.document'. Accessing global variables, such as 'var foo = 3; foo' does not need checks because the receiver is the inner window object.

  When an outer window is detached from its global context (when a frame navigates away from a page), it is completely detached from the inner window. A new context is created for the new page, and the outer global object is reused. At this point, the access check on the DOMWindow wrapper of the old context is turned on. The code in old context is still able to access DOMWindow properties, but it has to go through domain security checks.


It is debatable on how to implement the outer window object. Currently each property access function has to check if the receiver is ApiGlobalObject type. This approach might be error-prone that one may forget to check the receiver when adding new functions. It is unlikely a performance issue because accessing global variables are more common than 'window.foo' style coding.

I am still working on the ARM port, and I'd like to hear comments and suggestions on the best way to support it in V8.

4f7b6654d4 This change rewrites some of the code to add properties to an object. 
It removes the ReplaceConstantFunction code, and replaces it with
new ConvertDescriptorToField code, that is also used in other places.
Functions CopyRemove and CopyReplace on DescriptorArray are removed.
Function AddFastProperty is simplified by removing the 
CONSTANT_TRANSITION case.

76b1efea2d - Specialized slow-case string equality nine ways based on the 
underlying string representation of the two strings involved.
- Renamed ascii and two byte string classes to sequential ascii and
  sequential two byte, and renamed IsAscii and friends to
  IsAsciiRepresentation.  This is to make a clear distinction between
  strings with an ascii/two-byte representation, of which there is
  four, and flat sequential ascii/two-byte string.

c0e04e1e86 Fixed unsafe code where a GC could occour after a Handle had been deferenced. 
instances->set(i, *GetScriptWrapper(script));

GetScriptWrapper can call GC. The failure have only been seen on ARM, where
the g++ compiler pulls out the object from the instances handle to a register
before calling GetScriptWrapper causing set to be called on an object which
may have moved.

Marked a test on ARM as no longer flaky, whereas two other fails consistently
but that is no longer related to the problem fixed above.
