Only use the old ABI for FreeBSD 13 and earlier. Note: on the FreeBSD side, we will bump our libc++.so version for thi= s, and keep an old compatibility library in a separate package. Differential Revision: https://reviews.llvm.org/D126462 This ABI change can cause crashes when binaries compiled against older libc++ versions are run against binaries compiled against this libc++ version. For example, lang/ldc uses a precompiled bootstrap ldc2 binary that was compiled against the old libc++, but also links against libLLVM-15.so. If libLLVM-15.so is compiled against the new libc++ version, the ABI mismatch results in segfaults or even stack overflows. Note: we can only re-enable the std::pair trivial copy constructors again when the official libc++ ABI version is bumped to 2.
