So why does asan_report.cc have then:
static const char *MaybeDemangleGlobalName(const char *name) {
  // We can spoil names of globals with C linkage, so use an heuristic
  // approach to check if the name should be demangled.
  return (name[0] == '_' && name[1] == 'Z')
             ? Symbolizer::Get()->Demangle(name)
             : name;
}
and uses it where it wants to demangle?  From what I can see, even when
you are using llvm-symbolizer, sanitizer_common doesn't pass -demangle
option to it.
