Ng Zhi An f7ac5a2978 [wasm-simd][liftoff] Fix i64x2.mul codegen bug
When dst != lhs, we moved lhs to dst, but dst can be == rhs, so we would
overwrite rhs, and end up comparing lhs with itself, always returning
false. We handle the different aliasing cases in the macro-assembler
function I64x2GtS, to simplify the checks in Liftoff a little bit.
TurboFan does not need to change as it will require dst == lhs when AVX
is not supported.
