Not often; the optimizations enabled at the level tend to result in code
bloat (e.g. inlining allocation routines).  You have to be a bit careful
with -O5 too  -- for some time the fastest settings for the Mercury
compiler itself were -O4 --intermodule-optimization (I haven't checked
that recently though.)
