[PATCH] D33411: [Polly] Add handling of Top Level Regions

[Lukas Böhm via Phabricator via llvm-commits]

I extended the full-function.ll testcase to reflect that we now analyze the TLR.
Since the testcase was previously failing, this edit also adds a patch for `Scop::getRelativeLoopDepth`: It made use of `Region::outermostLoopInRegion` which has an unintuitive corner case for TLRs (which is documented), namely that it always returns `nullptr`.
