Remove i64x2 <-> f64x2 conversion opcodes - #178
Merged

Conversation
In the SIMD sync on 2020-01-14, we discussed the challenges with implementing these instructions in a performant way on 32-bit archs. And even on 64-bit arch, like x64, it requires AVX-512 for good codegen. There is consensus that because it is uncommon for such instructions to be used, and that hardware support is not widespread, we can remove these.
