For `vector bool` comparison one could use `vec_cmpeq` and `vec_compne` (see 
https://www.ibm.com/docs/en/xl-c-and-cpp-linux/16.1.1?topic=functions-vec-cmpeq).
 However, `vec_cmp*` interfaces do not currently support `vector pixel`. Do you 
have a concrete use case for comparing `vector pixel`s? If so I think we should 
consider adding corresponding overloads to `altivec.h`.
