This patch tidies up the llvm-strings testing by: 1. Adding comments to every test. 2. Getting rid of canned input files, and having the tests generate them on the fly (this makes the tests self-contained). 3. Adding missing test coverage. 4. Renaming some tests that weren't clear as to their purpose. 5. Adding extra checking of various cases, formatting etc. 6. Removing a test that didn't seem to have any useful purpose for testing llvm-strings. Reviewed by: rupprecht, grimar, MaskRay Differential Revision: https://reviews.llvm.org/D66015 llvm-svn: 368555
