[OpenMP] commit ea3f107a84eaa2459f6eb5d1c8dbeefea7576689 causes hangs on SPIRV

After https://github.com/llvm/llvm-project/commit/ea3f107a84eaa2459f6eb5d1c8dbeefea7576689, we see many hangs on SPIR-V, such as:

```

```

We need to investigate why, for now I plan to restrict the functionality added in this change to non-SPIRV.

Start by comparing commit ea3f107a84eaa2459f6eb5d1c8dbeefea7576689 with the preceding behavior, then run the listed libomptarget spirv64-intel tests to reproduce the hangs. Done means identifying the SPIR-V-specific regression and ensuring the affected tests no longer hang, whether through a targeted restriction or another confirmed fix.
