Message:

Make TypedArrays be available in commandline jsc
​https://bugs.webkit.org/show_bug.cgi?id=79163

Reviewed by Gavin Barraclough.

Adds a compile time option to have jsc support a basic implementation
of the TypedArrays available in WebCore. This lets us test the typed
array logic in the JIT witout having to build webcore.

• JSCTypedArrayStubs.h: Added.

(JSC):

• JavaScriptCore.xcodeproj/project.pbxproj:
• jsc.cpp:

(GlobalObject::finishCreation):
(GlobalObject):
(GlobalObject::addConstructableFunction):

• runtime/JSGlobalData.h:

(JSGlobalData):
