Winch is missing support for most of finished WebAssembly proposals. The goal of this issue is to track support for the SIMD proposal

Once we're working SIMD support, the cranelift Winch calling convention will need to be updated with whatever mechanism we choose. There's a TODO in the x64 abi introduced in #8210 that points out where we'll need to handle this for return values.

@MarinPostma I know @jeffcharles has plans to work on some of the unassigned instructions as well, so to keep the list tight and avoid duplicated effort, maybe we keep assigning them in batches?

no problem, then I'll take add, sub and mul for packed integer types, to begin with :)
