…droid (test-only) Reland of llvm#161624; depends on revert llvm#162001. - Android: keep %env_asan_opts=log_to_stderr=1. - Darwin: use CHECK-DAG for the pre-crash marker and header; frame line matches function only. - Common: reuse [[ADDR]]. NFC: test-only. Signed-off-by: Yixuan Cao <caoyixuan2019@email.szu.edu.cn>
