The hlfir::Entity to fir::ExtendedValue conversion usually uses the "fir base" output of hlfir.declare (which is the same as the input) to avoid introducing temporary descriptors for the sole purpose of introducing updating lower bound information. This is possible because local lower bounds, if any, are tracked in a vector inside the fir::ExtendedValue.

With assumed-ranks, the lower bounds cannot be tracked inside the fir::ExtendedValue vector (their numbers is unknown at compile time). Hence, the fir.box/fir.class used in fir::ExtendedValue in lowering must always contain accurate local lower bound information.
