Fix mixed input kind permute optimization

When change_vec_perm_layout runs into a permute combining two
nodes where one is invariant and one internal the partition of
one input can be -1 but the other might not be.  The following
supports this case by simply ignoring inputs with input partiton -1.

I'm not sure this is correct but it avoids ICEing when accessing
that partitions layout for gcc.target/i386/pr98928.c with the
change to avoid splitting store dataref groups during SLP discovery.

	* tree-vect-slp.cc (change_vec_perm_layout): Ignore an
	input partition of -1.
