rust tests: Do not run afoul of asm.validity.non-exhaustive in input-stats

This addresses one of the three test failures in https://github.com/rust-lang/rust/issues/142280

I was motivated to cover it myself because technically this is also compile-time UB if we compile a program that has asm! with x86-64-specific instructions on another platform. That'll only mean something if this is ever switched to build-pass, or if checking emits object code, but conveniently "nop" is valid assembly on all platforms anyone has implemented Rust codegen for. Even the weird ones LLVM doesn't support, like PA-RISC or Common Intermediate Language.

...except GPUs. Not sure about those.

...I don't understand why the test didn't fail in PR CI when I pushed it the first time?
