Bug 18327 – std.random.XorshiftEngine is parameterized by UIntType but only works with uint

The documentation says that std.random.XorshiftEngine uses a 32-bit algorithm but XorshiftEngine is parameterized by UIntType and permits non-uint UIntType but does not work correctly with them. The solution is to either make non-uint a compilation failure or to make XorshiftEngine support other UIntType.
