Prefer Clang over GCC for Objective-C(++)
GCC only has very limited support for Objective-C and doesn't support
any of the modern features, so whenever Clang is available, it should be
used instead. Essentially, the only reason to ever use GCC for
Objective-C is that Clang simply does not support the target system.
