Re: Is there an easy way to scan for bits?

Leif is correct.  The optimizer can do more for ILE than OPM (MI). Across a
series of dependent compute-intensive operations, this can make a big
difference in performance.   Ideally, you want most of the intermediate bit
values to be maintained in registers; the optimizer can do that for ILE.
In an MI program, intermediate results must be stored, which inhibits many
optimizations.

It might be faster because the optimizer does a very good job
and is used for C but not for MI. I had the same experience
when coding AES in both MI and C.
