Oops, ouch. Some clarifications: I don't have any silver bullet 
which makes everything run fast on every CPU. What I am saying
is that GCC provides defaults which fit into old i386 ABI. And some
requirements for new CPUs do not, so they are disabled by default.
That's why I am suggesting -m128bit-long-double, and that's it.
