Simplify rs6000_builtin_vectorized_function

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.

Tested on powerpc64-linux-gnu.

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