NFC: Ignore deprecation of asl_log in the runtime and demangling library.

ASL is deprecated in macOS 10.12. It may be time to transition to os_log now
that deployment targets have been raised to 10.12, but until that project
starts these warnings are just pollution.

Filed rdar://121066531 to track adoption of `os_log()` if appropriate.
