Summary: The clang-apply-replacements process is now invoked to apply replacements between applying transforms. This resulted in a massive simplification of the tool: - FileOverrides class no longer needed. - Change tracking and code formatting no longer needed. - No more dependency on libclangApplyReplacements. - Final syntax check is easier to do directly now than with a separate header/source pair. Replacement handling stuff abstracted into a new header/source pair to de-clutter ClangModernize.cpp somewhat. Tests updated.
