Make some tests LLVM-optimization agnostic and remove some others that were beyond value/repair
Several of these tests (the two deleted, and the one removal edit) were relying on the optimizer to collapse things to test some frontend feature. The tests were really old and features seemed amply covered by other parts of the test suite, so I just removed them. If anyone thinks they're valuable enough to keep/fix, we can play around with that, for sure. (inspired by r252872) llvm-svn: 253114
