but to wrap both an ASTUnit and a "string pool" that will be used for fast USR generation. This requires a bunch of mechanical changes, as there was a ton of code that assumed that CXTranslationUnit and ASTUnit* were the same. Along with this change, introduce CXStringBuf, which provides an llvm::SmallVector<char> backing for repeatedly generating CXStrings without a huge amount of malloc() traffic. This requires making some changes to the representation of CXString by renaming a few fields (but keeping the size of the object the same). llvm-svn: 119337
