Consider implementing Flexible Vectors Proposal for WebAssembly https://github.com/WebAssembly/flexible-vectors . Current Wasm SIMD operations are limited to 128 bit. With availability of Intel AVX2/AVX512 and ARM SVE, it will be nice to increase size of operands/registers for vector operations.
Initial and naive implementation in SpiderMonkey can just map/alias flexible vector operations to the existing Wasm SIMD (and add few more). Basically case of `vec.i8.length` := 16.
