Simplify ix86_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 x86_64-linux-gnu.

gcc/
	* config/i386/i386.c (ix86_builtin_vectorized_function): Remove
	entries that map directly to optabs.
