Change https://go.dev/cl/508715 mentions this issue: cmd/asm, cmd/internal/obj: generate proper atomic ops for riscv64

[mengzhuo]

@bcmills hi, can I add this issue to release-blocker?

[bcmills]

@mengzhuo, since riscv64 is not a first-class port it pretty much by definition can't be a release-blocker.

That said, I would expect that the fix can make the final go1.21.0 release anyway.

@gopherbot Please open backport issues.
