In #3809, a new extension to our fuzzing found that some of our Wasm-SIMD support requires nominally optional ISA features, at least on x86-64.
I think we should try to have fallbacks such that we can support all relevant features on any machine that supports the base ISA. On x86-64, this means just SSE2. Or if this is very difficult for some reason, we should document why and then possibly consider raising our minimum required ISA version.
