Log message:
	* tree-vect-transform.c (vectorizable_reduction): Support vectorization in
	the presence of multiple-data-types (i.e. - the vectorization factor is
	bigger than the number of elements in vectype for this operation).
	(vectorizable_operation): Add documentation. Fix support for constant and
	invariant operands.
	(vectorizable_store, vectorizable_load): Add documentation.
	* config/rs6000/altivec.md (sdot_prodv16qi): Pattern removed.
	
	* gcc.dg/vect/vect-120.c: Change to also test constant operands.
	* gcc.dg/vect/vect-reduc-dot-s8.c: Not vectorized on ppc.
	* gcc.dg/vect/vect-reduc-dot-u16.c: Remove unused variable.
	* gcc.dg/vect/vect-reduc-dot-s8s16.c: Removed.
	* gcc.dg/vect/vect-reduc-dot-u8s16: New.
