[libcxx-commits] [libcxx] Compile MSAN/TSAN failing test with -O1 (PR #73555)

[via libcxx-commits]

https://github.com/EricWF created https://github.com/llvm/llvm-project/pull/73555

This attempts to fix flakes on the bots where the modified test times out while running under sanitizers.

Turning on the optimizer for just this test appears to mostly fix the issue.
