----------------
Could you make all the `Descriptor&` and `Descriptor*` `const` ? The runtime will modify the value described by the descriptors, but it should not modify the descriptors themselves.

In lowering, `const Descriptor&` and `Descriptor&` do not end-up being handled the same in FIR (because FIR cares if descriptors may be modified in meaningful way by a function), so it's important to make them `const` when they are not intended to be modified by the runtime.
