This PR aims to fix #810 by crashing compilation whenever a mismatched gradient forward declaration is found.
There are two separate cases to handle the generated gradient code and search for a forward declaration.
If its a class/struct method, a lookup is performed in the class.
While if its a regular function, a lookup is performed in the TU.
Do let me know if any changes are necessary.
