* Enable SSE 4.2 unconditionally Fuzzing over the weekend found that `i64x2` comparison operators require `pcmpgtq` which is an SSE 4.2 instruction. Along the lines of #3816 this commit unconditionally enables and requires SSE 4.2 for compilation and fuzzing. It will no longer be possible to create a compiler for x86_64 with simd enabled if SSE 4.2 is disabled. * Update comment
