    System.Collections.IterateForEach<Int32>.ImmutableArray(Size: 512)

    Diff is small codegen diff in the inner loop.

    Also note this loop is down-countable and amenable to store sinking and such, really we shouldn't be looping at all (or the benchmark needs to merge all reads).

    Not quite sure how to unwedge this case. We start with something like
    

    Cross-block AP modifies the use of V7 in the loop:
    
    Then we duplicate the loop test block:
    
    Now both V04 and V07 are loop-carried, and have overlapping lifetimes.

    Seems like we could realize that the PHIs for V04 and V07 have identical VNs in both phi operands (we don't seem to add the VN for the backedge ones today) and decide that one of the two's uses could be replaced with the other. This would remove a loop-carried value and hopefully merge them into a single variable like we had before.

    I don't see how morph can anticipate this case; the problematic flow only gets created later.
