I believe the problem you ascribe to this bug is fixed.  Note that we do not
generate minss for the given example because "<=" is not the operation of the
minss instruction; it performs "<".  Which is relevant for "+0.0 < -0.0".

We *ought* to emit minss with -ffast-math, but that should happen via
noce_try_minmax invoking the sminsf3 pattern, rather than special-casing
this in the back-end.  Open a separate PR for that if you like.

But on the bright side, we at least generate a conditional move sequence:

        cmpless %xmm1, %xmm0
        andps   %xmm0, %xmm2
        andnps  %xmm1, %xmm0
        orps    %xmm2, %xmm0
