[cfe-commits] New clang warnings

[Ted Kremenek]

Thanks Anton.  I spent a good portion of my day yesterday getting rid  
of many of the strict-aliasing warnings in the AST library.  I plan on  
tackling the ones in the Analysis library soon.  I'll also take a look  
at the uninitialized value warning in CodeGen.
