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

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

[ScopInfo] Fix domains after loops. ISL can conclude additional conditions on parameters from restrictions on loop variables. Such conditions persist when leaving the loop and the loop variable is projected out. This results in a narrower domain for exiting the loop than entering it and is logically impossible for non-infinite loops. We fix this by not adding a lower bound i>=0 when constructing BB domains, but defer it to when also the upper bound it computed, which was done redundantly even before this patch. This reduces the number of LNT fails with -polly-process-unprofitable -polly-position=before-vectorizer from 8 to 6. llvm-svn: 264118
