information into the IR type codegen.  This allows a target to codegen the C
'double' type as either double or float.

This is a workaround until we figure out why a freshly create Preprocessor
doesn't expand macros from headers.

Shuffled around code in CFRefCount to better pair classes with implementation,
and started adding subclasses of RangedBugReport to handle better diagnostics
for reference count bugs.

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.

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.
