* tests: Drop -polly-detect-unprofitable and -polly-no-early-exitTobias Grosser2015-10-061-2/+2
| | | | | | | | 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

* Introduce the ScopExpander as a SCEVExpander replacementJohannes Doerfert2015-08-181-0/+63
The SCEVExpander cannot deal with all SCEVs Polly allows in all kinds of expressions. To this end we introduce a ScopExpander that handles the additional expressions separatly and falls back to the SCEVExpander for everything else.
