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.

After committing a change I had made to a few frontend tests, it was pointed
out to me that %T is being deprecated in LLVM in favor of %t. This change
simply converts usages of %T to %t while maintaining the integrity of the test.

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.

This option behaves in a similar spirit as -save-temps and writes
internal llvm statistics in json format to a file.
