EmitPathWarning into one method.  We now properly handle emitting warnings
without a PathDiagnosticClient when the warning does not involve a particular
statement.

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.

Added assertion if unexpected property decls are found where they don't belong.
Consolidated property decl. printing by using a helper function.

-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

Refactored LiveVariables to use getTerminatorCondition() in VisitTerminator().

Bug fix: CFG now computes Block-level expression numbers using information
from block terminators.  This fixes <rdar://problem/5868189>.

comments.  Comments to be restored later.

does work with single-line ones :).
