This does not yet have i64x2 version of the instructions in https://github.com/WebAssembly/simd/pull/395 yet, right?



================
Comment at: llvm/lib/Target/WebAssembly/WebAssemblyInstrSIMD.td:1279
+            (I32x4.vt (int_wasm_widen_signed
+              (I8x16.vt V128:$vec), (i32 timm:$idx))))],
+         "i32x4.widen_i8x16_s\t$dst, $vec, $idx",
----------------
I think this is the first time we use `timm` in this file... Haven't we used `LaneIdxN` for these? The same for `WIDEN_I8x16_TO_I32x4_U`.
