LOG: [WebAssembly] Renumber SIMD opcodes

Summary:
As described in https://github.com/WebAssembly/simd/pull/209. This is
the final reorganization of the SIMD opcode space before
standardization. It has been landed in concert with corresponding
changes in other projects in the WebAssembly SIMD ecosystem.
