The patch complements https://github.com/llvm/llvm-project/pull/68919 and adds AArch64 support for builtin `__builtin_cpu_supports("feature1+...+featureN")` which return true if all specified CPU features in argument are detected. Also compiler-rt aarch64 native run tests for features detection mechanism were added and 'cpu_model' check was fixed after its refactor merged https://github.com/llvm/llvm-project/pull/75635 Original RFC was https://reviews.llvm.org/D153153
