Add -isystem-prefix and -ino-system-prefix arguments, which can be used to override whether headers are system headers by checking for prefixes of the header name specified in the #include directive. This allows warnings to be disabled for third-party code which is found in specific subdirectories of include paths. llvm-svn: 158418
