`tests/codegen-llvm/scalable-vectors/tuple-intrinsics.rs` is broken

[jieyouxu]

Non-blocking on the fact that tests/codegen-llvm/scalable-vectors/tuple-intrinsics.rs was actually skipping FileCheck, due to its use of //@ build-pass, despite containing several FileCheck assertions.

In that test, skipping FileCheck seems to have been unintentional.

Unfortunately we can't just re-enable FileCheck for that test, because the current FileCheck assertions appear to be broken.
