bbafb8a745 Unify naming of LangOptions variable/get function across the Clang stack (Lex to AST). 
The member variable is always "LangOpts" and the member function is always "getLangOpts".

c000e7ed3d Add a basic CallGraph to Analysis. 
The final graph contains a single root node, which is a parent of all externally available functions(and 'main'). As well as a list of Parentless/Unreachable functions, which are either truly unreachable or are unreachable due to our analyses imprecision.

The analyzer checkers debug.DumpCallGraph or debug.ViewGraph can be used to look at the produced graph.

Currently, the graph is not very precise, for example, it entirely skips edges resulted from ObjC method calls.

57d736fd46 [analyzer] Use the new registration mechanism for the debugging info "checks". 
The relative checker package is 'debug':

'-dump-live-variables' is replaced by '-analyzer-checker=debug.DumpLiveVars'
'-cfg-view' is replaced by '-analyzer-checker=debug.ViewCFG'
'-cfg-dump' is replaced by '-analyzer-checker=debug.DumpCFG'
