[Mlir-commits] [mlir] [MLIR][test] Re-disable FileCheck on async.mlir integration test (PR #190702)

[Jared Hoberock]

https://github.com/jaredhoberock created https://github.com/llvm/llvm-project/pull/190702

#190563 re-enabled FileCheck on `Integration/GPU/CUDA/async.mlir`, but
the buildbot has shown intermittent wrong-output failures
([example](https://lab.llvm.org/buildbot/#/builders/116/builds/27026)):
the test produces `[42, 42]` instead of the expected `[84, 84]`.

This wrong-output flakiness is distinct from the cleanup-time
`cuModuleUnload` errors that #190563 actually fixes — it's the
underlying issue tracked by #170833. The merged commit message for
#190563 incorrectly says `Fixes #170833`; that issue should be
reopened, since the cleanup-error fix doesn't address the wrong-output
behavior.

This PR puts the test back in its previously-disabled state. The
runtime cleanup fix in #190563 is unaffected.

Subject: [PATCH] [MLIR][test] Re-disable FileCheck on async.mlir integration
 test

#190563 re-enabled FileCheck on Integration/GPU/CUDA/async.mlir, but
the buildbot has shown intermittent wrong-output failures: the test
produces [42, 42] instead of the expected [84, 84]. This is distinct
from the cleanup-time cuModuleUnload errors that #190563 actually
fixes; it is the underlying flakiness tracked by #170833.

Put the test back in its previously-disabled state.
