    [turbofan] Introduce CheckedUint32Div and CheckUint32Mod operators. · 15ebec03
    bmeurer authored
    Checked integer division and modulus can be done more efficiently
    if we know that the inputs are in Unsigned32 range.
    
    Drive-by-fix: Replace the TypeCheckKind on NodeInfo by a proper
    restriction type, and thread the feedback type through binary
    Number operations similar to what we do for their speculative
    versions. Also deal with Unsigned32 inputs for integer multiplication.
