After the previous patches it's no longer necessary for
TARGET_BUILTIN_VECTORIZED_FUNCTION to return functions that
map to the vector optab of the original operation.  We'll use
a vector form of the internal function instead.


gcc/
        * config/rs6000/rs6000.c (rs6000_builtin_vectorized_function): Remove
        entries that map directly to optabs.
