there is a GSOC project "Bits and Ints" that is working on a lot off this kind of branch less algorithms. I can suggest him to include the integer runtime variant of some math functions, as log2.
that would be nice ... it would be even nicer, if you could suggest to make use of hardware instructions ... i am currently using this gcc-centric code [1] ...

The GSOC project will make first a portable implementation. Once the portable implementation is finished, other architecture dependent implementation could be benchmarked and provided if they give better performances.
