I should also mention before I forget, it is theoretically possible to support v128 on all platforms. We are in control of our own ABI and we could say that the v128 type always maps to memory or a pair of u64 values. This would require rejiggering not only the Cranelift trampolines generated but additionally the WasmTy trait and how arguments are passed in the ABI. I figured that was a big lift for now where it'd be "much easier" to wait for Rust to add stable support for vector types on s390x and RISC-V in theory (in the assumption that users desiring that will coincide with a much later date in the future)
