This modifies the tool somewhat to only create files when about to run the "interestingness" test, and delete them immediately after - this means some more files will be created sometimes (when "double checking" work - which should probably be fixed/avoided anyway). This now creates temporary files, rather than only unique ones, and also uses ToolOutputFile (without ever calling "keep") to ensure the files are deleted as soon as the interestingness test is run. llvm-svn: 371696
