Clemens Hammacher a32cd1c710 Reland "[base] Introduce RoundUpToPowerOfTwo64" 
With fix for architectures where x<<32 != x.

Original change's description:
> [base] Introduce RoundUpToPowerOfTwo64
>
> And fix RoundUpToPowerOfTwo32 to return 1 for the input 0.
> 0 is no power of two.
> Beside being the correct value, this also avoids a special case in the
> (new) fast path using the number of leading zeros.
