Summary: ScalarEvolutionExpander assumes that the header block of a loop is a legal place to have a use for a phi node. This is true only for phis that are either in the header or dominate the header block, but it is not true for phi nodes that are strictly internal to the loop body. This change teaches ScalarEvolutionExpander to place uses of PHI nodes in the basic block the PHI nodes belong to. This is always legal, and `hoistIVInc` ensures that the said position dominates `IsomorphicInc`.
