Also add testcases for a bunch of expression forms that cause our evaluator to crash. See PR33140 and PR32864 for crashes that this was causing. This reverts r305287, which reverted r305239, which reverted r301742. The previous revert claimed that buildbots were broken, but did not add any testcases and the buildbots have lost all memory of what was wrong here. Changes to test/OpenMP are not reverted; another change has triggered those tests to change their output in the same way that r301742 did. llvm-svn: 306346
