Allow eager evaluated binary && and || conditions The domain generation can handle lazy && and || by default but eager evaluated expressions were dismissed as non-affine. With this patch we will allow arbitrary combinations of and/or bit-operations in the conditions of branches. Differential Revision: http://reviews.llvm.org/D13624 llvm-svn: 249971

Prepare unit tests for update to ISL 0.16 ISL 0.16 will change how sets are printed which breaks 117 unit tests that text-compare printed sets. This patch re-formats most of these unit tests using a script and small manual editing on top of that. When actually updating ISL, most work is done by just re-running the script to adapt to the changed output. Some tests that compare IR and tests with single CHECK-lines that can be easily updated manually are not included here. The re-format script will also be committed afterwards. The per-test formatter invocation command lines options will not be added in the near future because it is ad hoc and would overwrite the manual edits. Ideally it also shouldn't be required anymore because ISL's set printing has become more stable in 0.16. Differential Revision: http://reviews.llvm.org/D16095 llvm-svn: 257851
