[turbofan] Change TruncateFloat32ToUint64 to TryTruncateFloat32ToUint64. 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. I implemented the new operator on x64, arm64, and mips64. @v8-ppc-ports, can you please take care of the ppc64 implementation of the second output? 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.
