Anna Thomas 0691483435 [LV] Fix insertion point for shuffle vectors in first order recurrence
Summary:
In first order recurrence vectorization, when the previous value is a phi node, we need to
set the insertion point to the first non-phi node.
We can have the previous value being a phi node, due to the generation of new
IVs as part of trunc optimization [1].
