    [turbofan] Add support for transitioning stores to double fields. · 17a65191
    bmeurer authored
    This introduces an AllocateMutableHeapNumberStub for the boxed double
    field case, where we need to allocate a box in case of a transitioning
    store first. We cannot use our inline allocations for this currently,
    because mutable HeapNumber objects have certain alignment constraints,
    and I don't want to mess up Allocate/AllocateInNewSpace eagerly.
    
    Also refactor the PropertyAccessInfoFactory slightly to split the long
    methods into simpler parts.
