1. Instead of using individual "boolean" macros, have an "enum" macro `_LIBCPP_HARDENING_MODE`. This avoids issues with macros being mutually exclusive and makes overriding the hardening mode within a TU more straightforward. 2. Rename the safe mode to debug-lite. This brings the code in line with the RFC: https://discourse.llvm.org/t/rfc-hardening-in-libc/73925 Fixes #65101
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.
