Fix gcc.dg/vect/bb-slp-46.c FAIL

When relaxing vectorization of possibly overflowing reductions I
failed to update a testcase that will now vectorize and no longer
test for what it was written for.  The following replaces the
vectorizable add with a division.

	* gcc.dg/vect/bb-slp-46.c: Use division instead of addition
	to avoid reduction vectorization.
