[RegionInfo] Use RegionInfo* instead of RegionInfoPass* as graph type
This allows printing region graphs when only the RegionInfo (e.g. Region::getRegionInfo()), but no RegionInfoPass object is available. Specifically, we will use this to print RegionInfo graphs in the debugger. Differential version: http://reviews.llvm.org/D11874 Reviewed-by: grosser llvm-svn: 244442
