Hi, I built and tested clang using this patch and https://reviews.llvm.org/D118862. It works great.
The current patch adds the -darwin-target-variant flag to all object files for MacOS targets in the compiler_rt's builtin library. However, users building compiler_rt may have compilers that don't support such flag, so it would be nice to have a CMake option to enable compiler flags like `COMPILER_RT_ENABLE_CATALYST`.
