Chandler Carruth f3f955b5b9 FileCheck-ize a test that had the strangest TCL quote I've seen yet: an
opening single quote with no closing single quote, and with {} quotes
"inside" of it. This broke some of our tools that scrape test cases.

Also, while here, make the test actually assert what the comment says it
asserts. This was essentially authored by Nick Lewycky, and merely typed
in by myself. Let me know if this is still missing the mark, but the
previous test only succeeded due to the improper quoting preventing
*anything* from matching the grep -- it had a '4(%...)' sequence in the
output!
