This patch adds a configuration of the libc++ test suite that enables optimizations when building the tests. It also adds a new CI configuration to exercise this on a regular basis. This is added in the context of [1], which requires building with optimizations in order to hit the bug. [1]: https://github.com/llvm/llvm-project/issues/68552
