Global constructors should be configurable and not enumerable
https://bugs.webkit.org/show_bug.cgi?id=110573

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'.

It appears that this caused more glitches than it helped resize performance.
