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
libc++ / libc++abi configuration caches
This directory contains CMake caches for the supported configurations of libc++. Some of the configurations are specific to a vendor, others are generic and not tied to any vendor.
While we won't explicitly work to break configurations not listed here, any configuration not listed here is not explicitly supported. If you use or ship libc++ under a configuration not listed here, you should work with the libc++ maintainers to make it into a supported configuration and add it here.
Similarly, adding any new configuration that's not already covered must be discussed with the libc++ maintainers as it entails a maintenance burden.
