base/intmath.hh:
Don't return -1 in FloorLog2. That's wierd. Assert instead.
If you care about this, you should check for zero yourself.
Create seprate versions for uint32_t, uint64_t, int32_t, and
int64_t. signed vs unsigned so that error checking can be done
correctly. 32 vs 64 for speed.
Finally, fix a little bug in CeilLog2 that will make it return
the correct result for 1.
