Currently, the helpers to get fir::ExtendedValue out of hlfir::Entity use hlfir.declare second result (`#1`) in most cases. This is because this result is the same as the input and matches what FIR was getting before lowering to HLFIR. But this creates odd situations when both hlfir.declare are raw pointers and either result ends-up being used in the IR depending on whether the code was generated by a helper using fir::ExtendedValue, or via "pure HLFIR" helpers using the first result. This will typically prevent simple CSE and easy identification that two operation (e.g load/store) are touching the exact same memory location without using alias analysis or "manual detection" (looking for common hlfir.declare defining op). Hence, when hlfir.declare results are both raw pointers, use `#0` when producing `fir::ExtendedValue`. When `#0` is a fir.box, keep using `#1` because these are not the same. The only code change is in HLFIRTools.cpp and is pretty small, but there is a big test fallout of `#1` to `#0`.
