Prototype the newly proposed load_lane instructions, as specified in https://github.com/WebAssembly/simd/pull/350. Since these instructions are not available to origin trial users on Chrome stable, make them opt-in by only selecting them from intrinsics rather than normal ISel patterns. Since we only need rough prototypes to measure performance right now, this commit does not implement all the load and store patterns that would be necessary to make full use of the offset immediate. However, the full suite of offset tests is included to make it easy to track improvements in the future. Since these are the first instructions to have a memarg immediate as well as an additional immediate, the disassembler needed some additional hacks to be able to parse them correctly. Making that code more principled is left as future work.
