tests: Drop -polly-detect-unprofitable and -polly-no-early-exit These flags are now always passed to all tests and need to be disabled if not needed. Disabling these flags, rather than passing them to almost all tests, significantly simplfies our RUN: lines. llvm-svn: 249422

[isl-codegen]: Fix off by one in getNumberOfIterations We need to remove one dimension. Any is correct as long as it exists. We have choosen for whatever reason the dimension #dims - 2. This is incorrect if there is just one dimension. For CLooG this case did never happen. For isl however, the case can happen and causes undefined behavior including crashes. We choose now always the last dimension #dims - 1. We could have choosen dimension '0' but the last dimension is what we remove conceptionally in the algorithm, so it seems better to actually program it that way. While at it remove another piece of undefined behavior. llvm-svn: 174894
