[flang-commits] [flang] [flang][OpenMP] Add test for checking overloaded operator in atomic update (PR #88471)

[via flang-commits]

https://github.com/NimishMishra created https://github.com/llvm/llvm-project/pull/88471

Atomic update expression does not allow overloaded user-defined operators. This PR adds a test case for the same; the semantic check is already existent.
