    PPC/s390: [turbofan] Change Float64Max/Float64Min to JavaScript semantics. · aed69fd9

    Original commit message:
    
        So far we don't have a useful way to inline Math.max or Math.min in
        TurboFan optimized code. This adds new operators NumberMax and NumberMin
        and changes the Float64Max/Float64Min operators to have JavaScript
        semantics instead of the C++ semantics that it had previously.
    
        This also removes support for recognizing the tenary case in the
        CommonOperatorReducer, since that doesn't seem to have any positive
        impact (and actually doesn't show up in regular JavaScript, where
        people use Math.max/Math.min instead).
    
        Drive-by-fix: Also nuke the unused Float32Max/Float32Min operators.
