Optimize remaining simple 1-argument intrinsics.

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.
