* Treat global variables and parameters as non-differentiable when checking derivative data-flow Global parameters are by-default not differentiable (even if they are of a differentiable type), because our auto-diff passes do not touch anything outside of function bodies. The solution is to use wrapper objects with differentiable getter/setter methods (and we should provide a few such objects in the stdlib). Fixes: #3289 This is a potentially breaking change: User code that was previously working with global variables of a differentiable type will now throw an error (previously the gradient would be dropped without warning). The solution is to use `detach()` to keep same behavior as before or rewrite the access using differentiable getter/setter methods. * Fix issues with lookup witness lowering * Update slang-ir-lower-witness-lookup.cpp * Add tests * Update slang-ir-lower-witness-lookup.cpp * Cleanup * Update nested-assoc-types.slang --------- Co-authored-by: Yong He <yonghe@outlook.com>
