Add new RegionInfo pass. The RegionInfo pass detects single entry single exit regions in a function, where a region is defined as any subgraph that is connected to the remaining graph at only two spots. Furthermore an hierarchical region tree is built. Use it by calling "opt -regions analyze" or "opt -view-regions". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109089 91177308-0d34-0410-b5e6-96231b3b80d8
