    A simpler way to determine if a range spills only in deferred blocks, by · be7e4361

    validating that the hot path does not spill - somewhat simpler code.
    
    Cleared the scenario where a range is defined in a deferred block. The
    code before was slightly more complicated by not leveraging the
    property that these sort of ranges would be completely contained within
    deferred blocks.
    
    Moved "spills in deferred blocks" marking to a more appropriate
    location.
    
    One thing this CL achieves is correct support for scenarios where a
    range is spilled both on the deferred and then hot path, and the ranges
    concatenate. I owe better unit testing, which I will add in a subsequent
    CL.
