Specialization of StaticLog2<n> for n==0.
This specialization should never actually be used since log2(0) is negative infinity. However, since Log2() is often used to calculate the number of bits needed for a number, we might be using the value 0 with a conditional statement around the logarithm. Depending on the compiler the expansion of the template can occur before the conditional statement, so to avoid infinite recursion we need a specialization for the case n==0.
