Prototype i32x4.widen_i8x16_{s,u} (#3535)
As proposed in https://github.com/WebAssembly/simd/pull/395. Note that the other
instructions in the proposal have not been implemented in LLVM or in V8, so
there is no need to implement them in Binaryen right now either. This PR
introduces a new expression class for the new instructions because they uniquely
take an immediate argument identifying which portion of the input vector to
widen.
