When a loop has multiple reductions, each with an intermediate invariant store, the order in which those reductions are processed is not considered. This can result in the invariant stores outside the loop not preserving the original order. This patch sorts VPReductionPHIRecipes by the order in which they have stores in the original loop before running `InnerLoopVectorizer::fixReduction` function, and it helps to maintain the correct order of stores.
