Do not use STMT_VINFO_VECTYPE in vectorizable_reduction

There's one use of STMT_VINFO_VECTYPE in vectorizable_reduction
where I'm only 99% sure which SLP_TREE_VECTYPE to replace it with
(vectorizable_reduction needs a lot of post-only-SLP TLC).  The
following replaces it with the hopefully appropriate one.

	* tree-vect-loop.cc (vectorizable_reduction): Replace
	STMT_VINFO_VECTYPE use with SLP_TREE_VECTYPE.
