After discussion with ECMAScript committee, Uint8ClampedArray was change...

...d to no longer inherit from Uint8Array. Firefox never implemented this, so web compatibility impact should be minimal, and there are good arguments for keeping the types distinct because they do have differing behavior. (The original motivation was to allow Uint8ClampedArray instances coming from CanvasRenderingContext2D.getImageData to be passed to APIs taking Uint8Array, but this can be done with no copies simply by creating a new view against the same ArrayBuffer.)

Removed the invalidated test from the 1.0.2 conformance suite and updated the test (incompatibly) in the top of tree conformance suite.
