compiler: insert backend type conversion for closure func ptr
In Func_expression::do_get_backend when creating the backend
representation for a closure, create a backend type conversion to
account for potential differences between the closure struct type
(where the number of fields is dependent on the number of values
referenced in the closure) and the generic function descriptor type
(struct with single function pointer field).
