Replace uses of %T with %t in from previous frontend test differential

[justice_adams]

Summary

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.

Previous revision where this discussion took place: https://reviews.llvm.org/D50563

@stella.stamenova These are the changes from our previous discussion regarding the usage of %T

Normally when needing a directory you'd mkdir %t.dir before using it, but since you don't' want the directory to exist here this should be good as-is. Thanks!

@thakis thanks for the review. I don't have commit access, would you mind committing this for me?

[thakis]

Done, thanks for the patch!

The NetBSD buildbot breaks in these tests now:

http://lab.llvm.org:8011/builders/lldb-amd64-ninja-netbsd8/builds/18721

Both tests break in a similar way:

Please fix.

The NetBSD buildbot breaks in these tests now:

Pretty much every bot is red because of this patch (http://lab.llvm.org:8011/one_line_per_build) so yes, please fix.
