[WebAssembly] Add Defs = [ARGUMENTS] to SIMD_I

[aheejin]

Summary

rL344086 seems to have deleted it, and rL344180 tried to solve it by
adding Defs = [ARGUMENTS], which somehow broke the expensive check
bot. This patch adds this to SIMD_I as a temporary measure until we
land rL344180 again.

[tlively]

I fixed the issue in rL344287.
