This migrates the remaining Date builtins to C++ and removes obsolete
intrinsics and JavaScript wrappers. This reduces the overhead imposed
by the Date builtins, and will allow us to optimize them later in the
TurboFan compiler, while the interpreter doesn't need to worry about
them.

There's no reason to have JavaScript wrappers for those accessors,
since the meat is already in hand-written native code (via %_DateField).
First step now to put them into native builtins. Next step will be to
completely remove %_DateField.

Even though the change is ES6 spec compliant, we decided to revert
to be consistent with other browsers and work on fixing the spec.
Original issue's description:
> Make dates default to the local timezone if none specified
>
> In ES5, dates were supposed to default to UTC if no timezone was specified. However, this changed in ES6, which specified that dates should be in the local timezone if no timezone was specified. This CL updates our behavior to match that part of the ES6 spec.

This is a change for ES2015. Date objects have mutable state, so having
a mutable prototype is bad for SES requirements, and it is an
inconsistency from the typical ES2015 class style of objects

We used to call toString as a method which is not safe.

This fixes Date.prototyoe.toISOString to throw a RangeError exception
for invalid time values. It also includes a fix to removes the arbitrary
(and completely bogus) range limit on the date value during construction
of a Date object. Note that we still have bogus range limits on the year
and month values.

methods rely on the time values passed in being within a certain range
- not significantly larger than the the ECMA 262 specified time
range. When creating a time, always make it NaN if there is no way
that it can be within range even after UTC conversion.

In the shell sample don't print the result of executing a script, only
evaluating expressions.
Fixed issue when building samples on Windows using a shared V8
library. Added visibility option on Linux build which makes the
generated library 18% smaller.
Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.
Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.
Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.
