e9e8628380 Revert revisions 1383, 1384, 1391, 1398, 1401, 1402, 
1418, and 1419 from bleeding_edge until we have a fix
for the crashers we see on the distributed test infra-
structure.

We know that revision 1383 is causing issues, but I 
had to revert some of the other recent RegExp changes
in order to get this part out.

5b8c63f9d5 Avoids allocating a JSArray of capture information on each non-global 
regular expression match.
Also moves all last-match information into one place where it can be
updated from C++ code (this will be used in another afsnit).

c093e94546 - Pass the knowledge whether the old GC is compacting to the GC prologue and epilogue. This allows us to skip frame cooking and uncooking when doing a mark-sweep GC.

0c7af39737 Speed up access to global variables from eval scopes. Traverse the 
surrounding context to figure out if the variable could be global.  If
the variable could be global we check context extension objects at
runtime and use a global LoadIC if no variables have been introduced
by eval.

Fix crash bug when loading function arguments from inside eval.  The 
shadowed variable in the DYNAMIC_LOCAL case does not rewrite to a slot in 
that case.

d131ecf3dd Changed the debugger API to allow only one debug event listener to be registered. The public API now only has SetDebugEventListener instead of AddDebugEventListener and RemoveDebugEventListener. 
Moved the registrered debug event listener from the context to a global handle in the Debugger class. Storing it in the context did not make much sense.

Changed a lot of tests to handle the API change.

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.

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.

if object's map is the same as constructor's initial map. By copying maps, the constructor's
initial map is not changed.

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.

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.
