[PATCH] D35849: [UBSan] Provide default blacklist filename for UBSan

[Han Shen via Phabricator via cfe-commits]

shenhan created this revision.

This is to provide a default blacklist filename for UBSan.

While UBSan is turned on, it's better that clang pick up a blacklist file (when exists), just as what ASan / MSan does, so we do not end up adding the "-fsanitize-blacklist" option to every command line.
