Hot fix two test regressions (%T vs %t) Different Unix "errno" values are returned for the following scenarios: $ echo test > /tmp/existingFile/impossibleDir/impossibleFile "Not a directory" $ echo test > /tmp/nonexistentDir/impossibleFile "No such file or directory" This fixes the regression introduced by r352971 / D57592. llvm-svn: 352996

Fixed frontend clang tests in windows read-only container Summary: When mounting LLVM source into a windows container in read-only mode, certain tests fail. Ideally, we want all these tests to pass so that developers can mount the same source folder into multiple (windows) containers simultaneously, allowing them to build/test the same source code using various different configurations simultaneously. **Fix**: I've found that when attempting to open a file for writing on windows, if you don't have the correct permissions (trying to open a file for writing in a read-only folder), you get [Access is denied](https://support.microsoft.com/en-us/help/2623670/access-denied-or-other-errors-when-you-access-or-work-with-files-and-f). In llvm, we map this error message to a linux based error, see: https://github.com/llvm-mirror/llvm/blob/master/lib/Support/ErrorHandling.cpp This is why we see "Permission denied" in our output as opposed to the expected "No such file or directory", thus causing the tests to fail. I've changed the test locally to instead point to the root drive so that they can successfully bypass the Access is denied error when LLVM is mounted in as a read-only directory. This way, the test operate exactly the same, but we can get around the windows-complications of what error to expect in a read-only directory.
