Log:
Two changes to the get_best_mode interface

get_best_mode always returns a scalar_int_mode on success,
so this patch makes that explicit in the type system.  Also,
the "largest_mode" argument is used simply to provide a maximum
size, and in practice that size is always a compile-time constant,
even when the concept of variable-sized modes is added later.
The patch therefore passes the size directly.
