To make it possible for replacements made to headers as part of transforming one translation unit to not be visible to the transform of other translation units, Transform now handles replacement application as part of its end-of-source handling. Several things were simplified as a result: - The duplicated code in every transform for applying replacements is now gone and replaced with one location in Transform. - RefactoringTool is no longer used since Transform houses the Replacements structure. - RewriterContainer is now a private implementation detail of Transform (also renamed to RewriterManager since its behaviour is slightly different now with respect to lifetime of objects). - There's now no distinction between input and output file state. Misc notes: - Interface changes reflected in unit tests. - Replacements for files other than the main file are assumed to be for headers and stored as such. llvm-svn: 184194
