Thank you for fixing this.  I wanted to preserve this code but wasn't
sure about the correct place or whether it is still necessary.

There are more places we produce -0.  The regression tests have
alternative results to cover them.  I have the "float-zero" patch for
this.  Although I am not sure if it is a correct fix.  I think we
should find the correct fix, and apply it globally to floating point
operations.  This can be only enabled for platforms which produce -0,
so the others don't have to pay the price.
