It looks like we are increasing pat once too often, i.e., the loop body
while (pat[0] == '*' && pat < pat_end - 1)
pat++;
is executed twice instead of only once. Prior loop2, IL looks good to me. If
I'm exiting early in unroll_loop_runtime_iterations() in case max_unroll is
less or equal to 1, then it also works for me TM. Of course, this has nothing
to say for a latent bug.
