clang.cpp: InitializePreprocessor now makes a copy of the contents of PredefinesBuffer and
  passes it to the preprocessor object.
  
clang.cpp: DriverPreprocessorFactory now calls "InitializePreprocessor" instead of this being done in main().

html::HighlightMacros() now takes a PreprocessorFactory, allowing it to conjure up a new
Preprocessor to highlight macros.

class HTMLDiagnostics now takes a PreprocessorFactory* that it can use for html::HighlightMacros().
Updated clients of HTMLDiagnostics to use this new interface.

Handle text escaping (e.g. & -> &) last, to avoid interactions between 'replace' operations and insert operations.  This fixes a problem with "&;&" on line 666 of the gcc.c example I sent out.

While this adds no extra functionality now, we will soon pass the
PreprocessorFactory object to some ASTConsumers.

-Added TranslationUnitDecl class to serve as top declaration context
-ASTContext gets a TUDecl member and a getTranslationUnitDecl() function
-All ScopedDecls get the TUDecl as DeclContext when declared at global scope

the end.  It is now run at the same moment as in
llvm-gcc.  Also, run StripDeadPrototypes at the
end, just before running DeadTypeElimination.
This may be useful when doing LTO.  Note that
llvm-gcc runs StripDeadPrototypes but not
DeadTypeElimination.

Be more careful with insert_subreg and extract_subreg where either source or destination operand has already been coalesced with another register that's defined by a insert_subreg or extract_subreg.
