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.

converting the operands to 32-bit ints directly in the

c86b47f414 Rearrange the code in Scope::ResolveVariable.
I find this clearer and it also enables the DYNAMIC_LOCAL optimization
for code executed by eval that itself uses eval:

 eval("(function() { var x = 2; eval('1'); do stuff with x...; })()")

a09832ab76 Optimize loads from variables that might be shadowed by variables
introduced by eval.

In the cases where calls to eval have not introduced any variables, we
do not need to perform a runtime call.  Instead, we verify that the
context extension objects have not been created and perform a direct
load.

Not implemented for ARM yet and the scope resolution code could use
some better abstractions.  I'd like to do that in a separate
changelist.

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.

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.
