Summary: Introduces a utility library in Refactoring/ to collect routines related to source-code manipulation. In this change, we move "extended-range" functions from the FixIt library (in clangTooling) to this new library. We need to use this functionality in Refactoring/ and cannot access it if it resides in Tooling/, because that would cause clangToolingRefactor to depend on clangTooling, which would be a circular dependency.
