    X87: [wasm] Int64Lowering of I64Shl on ia32. · 8f506ac6

      original commit message:
      I64Shl is lowered to a new turbofan operator, WasmWord64Shl. The new
      operator takes 3 inputs, the low-word input, the high-word input, and
      the shift, and produces 2 output, the low-word output and the high-word
      output.
    
      At the moment I implemented the lowering only for ia32, but I think the
      CL is already big enough. I will add the other platforms in separate
      CLs.
