Aside from sqrt() and normalize(), we now optimize all the intrinsics which take a single argument as input, and return that argument with each of its components permuted as output. This CL also introduces a minor restriction--we no longer optimize intrinsics which evaluate to inf or nan, such as `inversesqrt(-1)`. These will be left in the source as-is.
