e8e35eccac Properly process arrays with overridden prototype in various Array's functions. 
Bailout to JS Array builtins if array's prototype is different from
Array.prototype.  Otherwise there might be inherited elements coming
from this prototype.

f54b7767c6 Implement fast load and call of arguments in the presence of eval. 
Load the arguments object from the context if there are no extensions
objects on the way. Then load the argument with a keyed load ic.

8d51195778 Fixed issue 619 allowing Object.create to be called with a function. 
This change allows Object.create to take a function as input in the
proto argument. The spec says that Type(O) for the proto argument
should be true but our IS_OBJECT does not check for this. I will make a
IS_SPEC_OBJECT in macros.py and refactor v8natives in another CL.

a83a88cd58 Moving more code to lookup an item from the native cache into code generator. 
To bypass expensive invocation of JS functions from C++ and omit runtime
call overhead for searching the cache, more elaborate deferred code is generated.

fb3e01a306 Correct issue 696 with Date.parse returning a value when called on a non date string. 
The error was introduced in revision 4557 where support was added for
ES5 date time format strings. Because there was no check for a valid
year a random string starting with a non-digit character would be
parsed.

This change disallows ES5 formatted dates where there is no date
fraction (i.e., with only a timestamp). Since none of the other
browsers support Date.parse on only timestamps I have disabled this
totally instead of just correcting the parser.

856135af42 Implement fast calls of functions in the presence of eval (if the eval 
calls do not introduce new bindings).

The infrastructure is already in place for fast loads from context
slots in the presence of eval.  This change simply uses that
infrastructure for calls as well as loads.

ToNumber()->Value() used as an int will throw a compile waring on

b8ba4deacc Reapply: Inline fast cases in string keyed load IC. 
(Fixed handling of out-of-bounds keys.)

String keyed load used to call STRING_CHAR_AT builtin that performs
two steps (get a char code, construct a one-char string from the
code), both of which have fast cases implemented as inline runtime
functions. In this chage most of the code from these functions is
extracted to a set of common generator functions in StringStubBase and
the fast cases are grouped together in the IC code.

The simple formula "ms = ticks * sampler_interval" doesn't work,
because e.g. on Linux, the actual sampling rate can be 5 times
lower than the one set up in the code. To calculate actual sampling
rate, current time is periodically queried and processed along with
actual sampling ticks count.

afc15bb48f Reapply load ICs for nonexistent properties. 
We need to be careful to check global property cells for the property
encountered during lookup.  Therefore, the ICs have to be specific to
the name of the property if global objects are involved.  In
principle, this means that we could get a large number of monomorphic
ICs for the same map if there is a global object in the prototype
chain.  However, since this is only done for normal load ICs and not
for keyed load ICs I do not expect this to be a problem.  I will
experiment with it once this goes in.

652335b995 Implement support for reattaching a global object to a context. This 
can be used to use the same global object for different contexts at
different points in time.

54f0a5b221 Expose debug context into the native code. This change is doing several things: 
1) Exposes Local<Context> v8::Debug::GetDebugContext().
Rationale: We can already get debugger context instance using various workarounds,
so exposing it explicitly in the API only makes things more clear.

2) Removes debugger.HasJavaScriptFrames() requirement for entering debugger context.
Rationale: Sometimes we'd like to call into debugger from the external native code.

3) Makes Debugger v8::Debug::Call execute on debugger context's global object.
Rationale: This is somewhat arguable, but temporary measure. We've agreed that we
should introduce a DebugAPI object that would expose necessary API in the debug-delay.
The problem is that it would take some time to define this API and it is not really
convenient to do that on the v8 land given the difference in v8 / host lifecycle.
The plan is to compose this API as a Debug.* wrapper outside v8 by means of exposing
debugger context's global object here, and once API settles down, upstream it to v8 and
start making Debug::Calls on this new DebugAPI object instead.

2bd9919788 StringToDouble rewritten not using String::Get and memory allocations. 
It converts the number to "canonical" form removing insignificant digits,
leading zerroes and spaces what guarantees to fit a fixed size buffer and
does not changes result of strtod.
