How about
Expect.equals(0x40000000, 0x04000000 << 4);
and
Expect.equals(0x4000000000000000, 0x0400000000000000 << 4);
?

Added (though my CL does not affect left shift operations).

     Expect.equals(-0x10000000000000000, -1 << 64);
     Expect.equals(0, ~-1);
     Expect.equals(-1, ~0);
 
     Expect.equals(0, 1 >> 160);
     Expect.equals(-1, -1 >> 160);
 
     Expect.equals(0x100000000000000001,
         0x100000000000000001 & 0x100000100F00000001);
     Expect.equals(0x1, 0x1 & 0x100000100F00000001);
