  Log Message:
  -----------
  [WebAssembly] Prototype `f32x4.relaxed_dot_bf16x8_add_f32`

As proposed in https://github.com/WebAssembly/relaxed-simd/issues/77. Only an
LLVM intrinsic and a clang builtin are implemented. Since there is no bfloat16
type, use u16 to represent the bfloats in the builtin function arguments.
