    amdgcn: Use unsigned types for udivsi3/umodsi3 libgcc helper args/return
    
    This patch changes the argument and return types for the libgcc __udivsi3
    and __umodsi3 helper functions for GCN to USItype instead of SItype.
    This is probably just cosmetic in practice.

            * config/gcn/lib2-divmod.c (__udivsi3, __umodsi3): Change argument and
            return types to USItype.
            * config/gcn/lib2-gcn.h (__udivsi3, __umodsi3): Update prototypes.
