Luke Lau f841ad30d7 [WebAssembly] Replace LOAD_SPLAT with SPLAT_VECTOR ...

Splats were selected by matching on uses of `build_vector` with
identical elements, but a while back a target independent node for
vector splatting was added.
This removes the WebAssembly specific LOAD_SPLAT intrinsic, and instead
makes SPLAT_VECTOR legal and adds patterns for splat loads.
