As @bnjbvr mentioned in bytecodealliance/cranelift#943 (comment), some cranelift users may not have the most recent SSE versions (e.g. SSE4.1). In these cases, we may need to provide alternate encodings or legalizations in order to implement certain SIMD instructions.

This is subsumed by #3810 I think: we should support Wasm-SIMD on x86-64 with SSE2 (the minimum required architecturally on x86-64) as well as with the more recent extensions. Closing in favor of #3810.
