    [turbofan] Add the RoundInt32ToFloat32 operator to turbofan. · e06f7d78
    ahaas authored
    The new operator converts an int32 input to float32. If the input cannot
    be represented exactly in float32, the value is rounded using the
    round-ties-even rounding mode (the default rounding mode).
    
    I provide implementations of the new operator for x64, ia32, arm, arm64,
    mips, mips64, ppc, and ppc64.
