Require equal shift amounts for IFN_DIV_POW2
IFN_DIV_POW2 currently requires all elements to be shifted by the
same amount, in a similar way as for WIDEN_LSHIFT_EXPR. This patch
enforces that when building the SLP tree.
If in future targets want to support IFN_DIV_POW2 without this
restriction, we'll probably need the kind of vector-vector/
vector-scalar split that we already have for normal shifts.

in an IFN_DIV_POW2 node to be equal.
