Most of loop-doloop.c is wrapped by
#ifdef HAVE_doloop_end
<...>
#endif
so on my bootstraps/builds, it doesn't exercise the code. It was
pointed out to me the restructuring broke this file on some targets.
This should fix it by calling the refactored get_max_loop_iterations()
function. cross compiled for rs6000 to verify compilation.
