The spec got rid of `CheckObjectCoercible` a while back, and so should
we. This change is not observable in most of the affected cases since
`ToObject` is up near the top of most Array method algorithms. An
example of an observable effect of this change occurs for the following
input:
Array.prototype.sort.call(null, 1);
Behavior before applying the patch (incorrect message):
TypeError: Array.prototype.sort called on null or undefined
Expected behavior:
TypeError: The comparison function must be either a function or
undefined
This patch removes `CheckObjectCoercible` and adds tests to ensure the
few observable cases are addressed correctly.
The patch also adds a missing `ToObject(this)` to
`Array.prototype.lastIndexOf` which would otherwise become observable
as a result of `CheckObjectCoercible` being removed.

Do not allow that holey properties are defined in Array sort.
Throw a type error if the array is not extensible and there are holey
properties in the middle of the array.

This fixes another bug in Array.prototype.sort (when the array is not a
JSArray and there is a proxy on the prototype chain).

The spec says ToObject is called on the receiver, and this is
observable if you call sort on a primitive. This patch trivially
adds the call and a test.

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.
