When given unsaved files in clang_createTranslationUnitFromSourceFile,
copy the source buffers provided rather than referencing them
directly, so that the caller can free those buffers immediately after
calling clang_createTranslationUnitFromSourceFile(). Otherwise, we
risk hitting those buffers later (when building source ranges, forming
diagnostics, etc.).
