I don't mind this experimental code in repo, but let's do a few cleanups to
match with other experimental hacks we have!

 *) Change tty->print-s to log_develop_trace(gc); that also fixes tty->print vs.
tty->print_cr.

 *) Prefix new bug comments with FIXME

 *) Crush bad formatting early:
     - ConnectionHeuristics::choose_collection_set: indenting, 2 vs 3 spaces?
     - ShenandoahCollectorPolicy::phase_times() definition, excess space
     - globals.hpp, align right "\" around new additions

 *) UseShenandoahOWST in globals.hpp moved accidentally?

Otherwise looks okay.

Thanks,
