[llvm] [PGO] Add REQUIRES to test (PR #169531)

[Joel E. Denny via llvm-commits]

https://github.com/jdenny-ornl created https://github.com/llvm/llvm-project/pull/169531

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/31643
- https://lab.llvm.org/buildbot/#/builders/65/builds/25949
- https://lab.llvm.org/buildbot/#/builders/154/builds/24417

d69e70149636efa0293310303878fbf9a5f31433 did not fix the failure. Hopefully this will.
