Loop peeling also has an impact on the induction variables, so we should
benefit from induction variable simplification after peeling too.

PowerPC

The cost of splitting a large vector instruction is not being taken into account by the getUserCost function. This was leading to some loops being over unrolled. The cost of a vector instruction is now being multiplied by the cost of the type legalization. This will return a more accurate cost.
