pass3 step1 should use x86_64 optimization levels #84

Description

@briedel

Default the optimizations levels are still turned off because npx is old....

There are alternatives to what we do now with the awk script:

    Specifically, we need a builder that can build the new optimization levels. The current stratum0 can't do this, but I did test the code on a new NPX machine.
