[llvm] [PGO] Add missing target datalayout in test (PR #169520)

[Joel E. Denny via llvm-commits]

https://github.com/jdenny-ornl created https://github.com/llvm/llvm-project/pull/169520

The test was added by b8ef25aa643761233dc5b74d9fb7c38a2064d9c7.  It failed on at least the following bots, but the failure did not reproduce on my test machines or in pre-commit CI:

- https://lab.llvm.org/buildbot/#/builders/190/builds/31638
- https://lab.llvm.org/buildbot/#/builders/190/builds/31638

This fix hopefully addresses at least the warnings there.
