State-Changed-Why:
    Problem confirmed.  GCC currently uses __umoddi3 from
    libgcc2.c for the operation.  We need to add pattern
    to allow use of $$rem2U when available.  We don't
    currently have this routine in the millicode routines
    used with linux.
    
    I suspect there may be other 64-bit operations that
    are pessimized by using generic libgcc code.
