Original change's description:
> [wasm-simd][arm] Use vmov to move all ones to register
> 
> vceq(dst, dst, dst) does not seem to always set the register to all
> ones. The right way should be be to use vmov (immediate) anyway. This
> was not supported in the assembler yet, so we need changes to the
> assembler, diassembler, and simulator.
> 
> There is an unfortunate fork in logic in the simulator, due to the way
> the switches are set up, vmov (imm) logic is duplicated across two
> different cases, because the switch looks at the top bit of the
> immediate. Refactoring this will be a bigger change that is irrelevant
> for this bug, so I'm putting that off for now. Instead we extract the
> core of vmov (imm) into helpers and call it in the two cases.
