    Remove assembly coded log2 function
    
    As we move to supporting other systems we need to get rid of assembly
    where we can. The log2 function in src/lib is identical to the assembly
    one (tested for all 32-bit signed integers :-) and takes about 10 ns
    to run as opposed to 5ns for the non-portable assembly version. While speed
    is good, I think we can spare the 15 ns or so we add to boot time
    by using the C version only.
