/* Test that functions that have SIMD clone counterparts are not
cloned by IPA-cp. For example, special_add() below has SIMD clones
created for it. However, if IPA-cp later decides to clone a
specialization of special_add(x, 666) when analyzing fillit(), we
will forever keep the vectorizer from using the SIMD versions of
special_add in a loop.
If IPA-CP gets taught how to adjust the SIMD clones as well, this
test could be removed. */
