This didn't quite work - compiler-rt doesn't even link after this
change:

  Undefined symbols for architecture x86_64:
    "typeinfo for __cxxabiv1::__class_type_info", referenced from:
        __ubsan::checkDynamicType(void*, void*, unsigned long) in ubsan_type_hash.cc.o
        isDerivedFromAtOffset(__cxxabiv1::__class_type_info const*, __cxxabiv1::__class_type_info const*, long) in ubsan_type_hash.cc.o
        findBaseAtOffset(__cxxabiv1::__class_type_info const*, long) in ubsan_type_hash.cc.o

See here:

I've reverted both r233071 and r233036 in r233097 to get things working
again.
