This CL changes Array.p.fill to use the baseline implementation
for everything other than JSArray.
One of the reasons is that shadowing the length property on
TypedArrays (and other ElementsKinds) is allowed and should be
respected by Array.p.fill. The fast-path for fill for TypedArrays
expects the indices to be clamped to the actual length of the
underlying backing store and not to some length property.
While this mismatch (and others) could probably be handled properly,
we do the conservative thing and only use the fast-path for specific
JSArrays.
