Added quoting of the name of the ref property using {"ref":1} instead of {ref:1}. The Chrome C++ JSON parser implementation requires quoted property names.
Changed the JSON format for non finite numbers. The previous formatting using NaN, Infinite and -Infinite caused the Chrome C++ JSON parser implementation to fail. Values "NaN", "Infinite" and "-Infinite" (incuding quotes) are now used.
Reverted changes to DebugLookupResultValue (runtime.cc) from http://codereview.chromium.org/17377. The change caused callback into Chrome with the current V8 context expected to have a DOM Window global object. This is not the case when the debugger context is the active context. This causes properties from interceptors and accessors to be reported as undefined in the debugger.

it is assigned a numeric handle. Handles are used to make a 1:1
correspondence between objects and mirrors. Currently the mirrors are
cached in a JavaScript array and when creating a mirror this cache is
checked to see if a mirror already exists for the object. This cache is
cleared when leaving the debugger.
Changed the serialization format to take advantage of these handles. When
an object is serialized referenced objects are represented just by their
handle id serialized as '{ref:<handle>}'. During serialization the
referenced handles are collected and the serializer can provide a
serialization of all the referenced objects.
Removed the special handling of array properties. Indexed properties and
the length property are now rendered as named properties in the
serialization.
Removed the special serialization handling of RegExp properties. The
properties 'source', 'global', 'ignoreCase' and 'multiline' are serialized
with the rest of the properties.
Changed a lot of tests to handle the changed format.

instead of normal JSObjects.
This ensures that __proto__ and accessors on the Object prototype do
not interfere with catch scopes. Also, it fixes the bug that catch
variables were not DontDelete (issue 74).
Next step is to create special lookup routines for context extension
objects and remove the special handling of context extension objects
from the general javascript object lookup routines.

The problem is that Disable/EnableAccessCheck on an object may chnage its constructor's behavior
if object's map is the same as constructor's initial map. By copying maps, the constructor's
initial map is not changed.

Properties from interceptors are also reflected through PropertyMirror as the distinction did not make sense seen from a JavaScript debugging perspective. The isNative function on a PropertyMirror can be used to check whether a property is defined natively by the host (or V8).
Simplified the local property lookup in the debug runtime call to just call GetProperty as the property is known to be a local property.

This can lead to large objects which wastes a lot of space if we normalize properties. We therfore clear the inobject properties when normalizing properties. This is done by adjusting the instance size in the new map and overwriting the inobject properties with a filler.

calling a stub. The map to check against is unknown when generating
the code, so we patch the map check in the IC initialization code.
Loop nesting is currently not tracked on ARM. I'll file feature
request bug reports for implementing this on ARM and add the number to
the TODOs before I commit.

the alternatives in a choice node. The quick checks
are conservative in the sense that they only detect
failure with certainty. Checks can do 2 or 4 characters
at a time.
* Inline the quick checks to allow the alternatives to
be checked without branching in the common case where
they fail.

- Removed the potential for a NULL pointer access in
ContextSwitcher::PreemptionReceived.
- Removed a leak of the semaphore in the ContexSwitcher thread, by removing
the need for this semaphore entirely.
- Added a regression test case which will catch accesses to the ContextSwitcher
singleton after it has been stopped.

void CodeForStatement(Node* node)
void CodeForSourcePosition(int pos)
The first is used to indicate that code is about to be generated for the given statement and the second is used to indicate that code is about to be generated for the given source position.
Added position information for some statements which was missing whem.
Updated the code generator for ARM to emit source position the same way as for IA-32.
Added an assert to ensure that deferred code stubs will always have a source source position as if it has not it will take whatever source position before which makes no sense.
The passing test on ARM has only been tested using the simulator.

code to think the pattern was equal to the atom and use the pattern
in the indexOf operation.

The main goal was to improve O(n^2) behavior when there are many object groups. The old API required the grouping to be done on the v8 side, along with a linear search. The new interface requires the caller to do the grouping, passing V8 entire groups at a time. This removes the group id concept on the v8 side.
- Changed AddObjectToGroup to AddObjectGroup.
- Removed the group id concept from the V8 side.
- Remove a static constructor while I'm here, lazily initialize
the object groups list.
- Cleaned up return by non-const references to return pointers.

initial node is interested in what precedes it the automaton is
given an initial all-consuming character class that determines it.
- Added verification of some node information invariants. We now
check that if a node expresses interest in what precedes it that
information is available to it after assertion expansion.
