Are there intrinsics for bitwise rotation available in LDC?

I just found this

    ulong rotateLeft(ulong x, ubyte bits)
    {
        return (x << bits) | (x >> (64 - bits));
    }

Questions:
- Is this a good implementation for the ulong case?
- Should we use >> or >>> ?
- What's the preferred type for `bits`, ubyte, or uint or making 
it a template parameter?
