ScopDetection: Only detect scops that have at least one read and one write Scops that only read seem generally uninteresting and scops that only write are most likely initializations where there is also little to optimize. To not waste compile time we bail early. Differential Revision: http://reviews.llvm.org/D7735 llvm-svn: 229820

Improve test coverage for non-affine access functions We now verify that such functions are correctly detected even in combination with delinearization. This change is added to ensure we have good test coverage for the subsequent delinearization fix. We also remove unnecessary instructions from the test case. llvm-svn: 217664
