[PATCH] D30691: [analyzer] Support for naive cross translational unit analysis

[Benjamin Kramer via cfe-commits]

Frontend depends on StaticAnalyzerCore by
including "clang/StaticAnalyzer/Core/Analyses.def". That's a clear layering
violation, but cmake doesn't model header dependencies. Maybe Analyses.def
should move into its own library.
