Reviewed by Geoffrey Garen.

Source/JavaScriptCore:

Update JSObject::deleteProperty() so that mark to set the property
value to undefined if it is in static hashtable of properties. The
previous code was not doing anything in this case and this meant
we could not remove builtin DOMWindow properties such as
"ProgressEvent" even if marked as Deletable.

Source/WebCore:

Update JSC Code generator so that global constructors now have the following
attributes:
{ [[Writable]]: true, [[Enumerable]]: false, [[Configurable]]: true }
instead of previously:
{ [[Writable]]: true, [[Enumerable]]: true, [[Configurable]]: false }

The new behavior is according to the Web IDL specification (section 4.4):
http://dev.w3.org/cvsweb/~checkout~/2006/webapi/WebIDL/Overview.html?rev=1.617;content-type=text%2Fhtml#es-interfaces

This also matches the behavior of Firefox.

LayoutTests:

Add new tests to make sure that the global constructors have the
right attributes and to check that they are 'Deletable'.

* canvas/philip/tests/type.delete-expected.txt: Removed.
* canvas/philip/tests/type.delete.html: Removed. It was checking that global constructor
could NOT be deleted, which is no longer according to the Web IDL specification.
* fast/dom/constructed-objects-prototypes-expected.txt:
* fast/dom/script-tests/constructed-objects-prototypes.js: Update test to hardcode a few
global constructors as they are no longer enumerable.
* fast/js/getOwnPropertyDescriptor-expected.txt:
* fast/js/global-constructors.html: Removed. It was relying on the global constructors
to be 'Enumerable', which is not to the latest Web IDL specification.
