emaste a1af6319dc llvm: remove __FreeBSD_version conditionals
All supported FreeBSD build host versions have backtrace.h, so we can
just eliminate that test.  For futimes() we can test the compiler's
built-in __FreeBSD__ major version rather than relying on including
osreldate.h.  This should reduce the frequency with which Clang gets
rebuilt when building world.
