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

Check feasibility for the runtime check context wrt. the domain. If nothing is executed we can bail out early. Otherwise we can use the constraints that ensure at least one statement is executed for simplification. llvm-svn: 245585
