8a731355be Make sure that eval and try-catch introduced context extension objects
act as if they have no properties in their prototype chains.

0dab442be9 Added handling of hidden prototype objects when collecting local properties for an object mirror. The property names provided by an object mirror now includes all properties from the object and any hidden prototypes merged together.
Changed the name of Runtime_GetPrototype to Runtime_DebugGetPrototype to indicate that it is a debugger related function and changed its implementation to do the correct __proto__ lookup.

Added some more information to the Map debug print.

e801020724 Marked ascii-regexp-subject as flaky on arm for now. The cause of
this failure is that this test depends on a particular optimization in
jscre that we don't yet have, but that we will get very soon.

f5f1cd2921 Changes to the V8 debugger support which otherwise caused problems with Chrome.
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.

c2c780bfc4 Added handles to the mirror objects. When a mirror for an object is created
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.

47d1298236 Change the handling of catch blocks to use context extension objects
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.

Accessor setters should not be called for eval-introduced context

This change fixes the issue, but I think it is time to separate out

There is no reason to use the general lookup routines for this.  I'll
do that in a separate changelist.

25112aba44 Refactored the mirror representation of properties. Removed the AssessorMirror and InterceptorPropertyMirror and moved all reflection for properties to PropertyMirror. From a PropertyMirror it can be checked whether a property has getter/setter defined in JavaScript and information on the getter/setter functions are now available. If calling the getter resulted in an exception this is reflected as well.
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.

12854e6c67 Allocate as many object-literal properties as possible inobject.
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.

void CodeForStatement(Node* node)

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.

6297a19160 Improve mark-compact object grouping interface.
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.

ff3e30ae11 - Added lookbehind propagation for the initial node; now, if the
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.

e8b56e6f95 Make sure that the API does not change templates pass in from the
user.  The API should never change templates behind the back of the
user.

d63a3e13e6 Changed the debugger break handling to support situations where there are no stack frames. This can happen when an exception is thrown when compiling code.
This is related to Chromium issue 5349 (http://code.google.com/p/chromium/issues/detail?id=5349).
