[PATCH] D21254: [asan] Do not instrument pointers with address space attributes

Do not instrument pointers with address space attributes since we cannot track them anyway. Instrumenting them results in false positives in ASan and a compiler crash in TSan. (The compiler should not crash in any case, but that's a different problem.)
