Benjamin Kramer fdacdb26af Use intrusive refcounted pointers to manage RopeRefCountString lifetime. 
std::shared_ptr<char []> would be even nicer, but shared_ptr doesn't work
with arrays :(

No functionality change.

Alp Toker 0621cb2e7d Make clang's rewrite engine a core feature 
The rewrite facility's footprint is small so it's not worth going to these
lengths to support disabling at configure time, particularly since key compiler
features now depend on it.

Meanwhile the Objective-C rewriters have been moved under the
ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still
potentially worth excluding from lightweight builds.

Tests are now passing with any combination of feature flags. The flags
historically haven't been tested by LLVM's build servers so caveat emptor.

Ted Kremenek cdf814900d Split library clangRewrite into clangRewriteCore and clangRewriteFrontend. 
This is similar to how we divide up the StaticAnalyzer libraries to separate
core functionality to what is clearly associated with Frontend actions.

Chris Lattner 0e62c1cc0b remove unneeded llvm:: namespace qualifiers on some core types now that LLVM.h imports 
them into the clang namespace.

Chris Lattner 48eb14dd79 Fix: 
Decl.cpp:716:28: warning: initialization of pointer of type 'clang::VarDecl *' from literal 'false' [-Wbool-conversions]
  VarDecl *LastTentative = false;

Ted Kremenek 2e385f9319 Call 'clear()' in ~RopePieceBTreeLeaf(), decrementing the reference 
counts of the bufffers referened by the RopePieces in
RopePieceBTreeLeaf.  This (I believe) corrently fixes the leak I meant
to fix in r84601 (which ended up causing an overrelease).

Ted Kremenek 2f9876cf7c Fix a reference count imbalance in RewriteRope::MakeRopeString(). 
This was causing a ton of memory to be leaked when using HTML
diagnostics with the static analyzer (on large files with many errors).

Chris Lattner 492530d2df simplify the implementation of the insert/split operation to return 
the new RHS directly instead of indirecting through the 'InsertResult'
struct.  This eliminates InsertResult.
