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

Introduce the ScopExpander as a SCEVExpander replacement 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.
