    PPC: [turbofan] Change TruncateFloat32ToUint64 to TryTruncateFloat32ToUint64. · 9418a710

    Original commit message:
        TryTruncateFloat32ToUint64 converts a float32 to a uint64. Additionally it
        provides an optional second return value which indicates whether the conversion
        succeeded (i.e. float32 value was within uint64 range) or not.
    
        Additionally I fixed a bug on x64 and mips64 in the implementation of
        TryTruncateFloat64ToUint64. Cases where the input value was between -1 and 0
        were handled incorrectly.
