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.

path separators as well as case sensitivity of the "no" in "no such file or directory." Rather than revert this file back to its original form, I've made some incredibly ugly regexes so that it will pass everywhere.
Note, the path this test reports a failure on (for my Windows setup) is: E:\llvm\llvm\tools\clang\test\Frontend/doesnotexist/somename

* Use a single stat to find out if the file exists and if it is a regular file.
* Use early returns when possible.
* Add comments explaining why we have each check.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
