Prototype SIMD extending pairwise add instructions (#3466)

As proposed in https://github.com/WebAssembly/simd/pull/380, using the opcodes
used in LLVM and V8. Since these opcodes overlap with the opcodes of
i64x2.all_true and i64x2.any_true, which have long since been removed from the
SIMD proposal, this PR also removes those instructions.
