It seems the parameters no longer do anything. i.e. -flto --param

Hi.
You are right, the param '--param ipa-cp-unit-growth' is really unused.
It's cause by Martin's commit f7725a488382, where we again reinvented
renamed param name. It will be fixed with the following obvious commit.
I'm going to install it once git will be opened for committing.
