can decide the policy on how to cache related bugs.  This allows us to
properly to handle warning about multiple leaks in the same location in the
ref count checker (not yet done).

rather than having it suck them out of a node.  Add
a bunch of new libcalls, and remove dead softfloat
code (dead, because FloatToInt is used not Expand
in this case).  Note that indexed stores probably
aren't handled properly, likewise for loads.

This is a workaround until we figure out why a freshly create Preprocessor

Shuffled around code in CFRefCount to better pair classes with implementation,

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.
