The TargetRegistry is just a namespace-like class, instantiated in one place to use a range-based for loop. Instead, expose access to the registry via a range-based 'targets()' function instead. This makes most uses a bit awkward/more verbose - but eventually we should just add a range-based find_if function which will streamline these functions. I'm happy to mkae them a bit awkward in the interim as encouragement to improve the algorithms in time. llvm-svn: 237059
