"AppleClang" is some strange fork with some features (both compiler and library) omitted or broken. OpenMP, for example, is one thing I've been missing for a good while; I've not checked if that's now present with new releases. I can understand adding extra functionality to a fork, like Objective C and swift stuff, but dropping bits is strange. It's due to issues like this that I do all our clang testing on FreeBSD, where it's a more vanilla build of the llvm codebase, and I treat AppleClang as a wholly separate compiler variant which requires independent testing.
