A new Clang-based tool which converts for loops to use the range-based syntax new to C++11. Three kinds of loops can be converted: - Loops over statically allocated arrays - Loops over containers, using iterators - Loops over array-like containers, using operator[] and at() Each transformation is assigned a confidence level by the tool. The minimum require confidence level to actually apply the transformation can be specified on the command line, but the default level should be fine for most code. Like other tools based on RefactoringTool, it is easiest to use this tool with a compilation database. llvm-svn: 162627
