The slow test tests SmiLexicographicCompare on a large number of Smi comparisons;
we can disable this test for some debug/noopt builds without losing much coverage.

To stay compatible with JSC, Array.p.sort did a post-processing step
that shadowed elements from the prototype chain.
Some time ago, JSC changed and no longer exhibits this behavior. To
preserve comptibility and stay consistent with RemoveArrayHoles,
this CL removes this post-processing step altogether and adjusts
tests to expect the new behavior.

This CL implements the functionality of SafeRemoveArrayHoles (JS),
which is used as a pre-processing step for sorting, in a runtime
function.
SafeRemoveArrayHoles is a generic fallback, when an existing runtime
function fails to remove holes/move undefineds to the end of an array.
This CL extends the existing runtime function to also support JSProxy
objects, and objects where indices have accessors.

This adds tests for 'oddly' behaving comparison functions.
I.e. functions that cause an element kind change and/or
modify the array. The tests check that sort does not crash in these
instances.

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.

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.
