Hmm, kind of.  The memory consumption goes down to 300MB and you have
knob (--param large-function-growth) to control how much of bloat you
want. 

Now we really should to figure out why RTL part of optimizer is taking
that much memory and time and avoid it/make it to give up.  So I think
it should stay open until then.  I will try to do some testing in
foreseable future, but the problem of unlimited function growth due to
inlining of functions called once is in general solved.
