    [turbofan] Avoid introducing machine operators during typed lowering. · 5bed1516
    bmeurer authored
    Introducing machine operators early causes trouble for the typing,
    truncation analysis and representation selection, so we should rather
    stick to simplified operators instead. Now there's only the for-in case
    left, which is not clear how we can handle this in a better way.
    
    Drive-by-fix: Also don't introduce Int32Constant and Word32Shl in
    JSTypedLowering, but use NumberConstant and proper NumberShiftLeft
    operators instead.
