Summary: This is the follow-up patch to D37924. This change refactors clang to use the the newly added section headers in SpecialCaseList to specify which sanitizers blacklists entries should apply to, like so: [cfi-vcall] fun:*bad_vcall* [cfi-derived-cast|cfi-unrelated-cast] fun:*bad_cast* The SanitizerSpecialCaseList class has been added to allow querying by SanitizerMask, and SanitizerBlacklist and its downstream users have been updated to provide that information. Old blacklists not using sections will continue to function identically since the blacklist entries will be placed into a '[*]' section by default matching against all sanitizers.
