At this point this is largely cosmetic, but it opens the door to replace
ProgramStateRef with a smart pointer that more eagerly acts in the role
of reclaiming unused ProgramState objects.

(Stmt*,LocationContext*) pairs to SVals instead of Stmt* to SVals.

This is needed to support basic IPA via inlining.  Without this, we cannot tell
if a Stmt* binding is part of the current analysis scope (StackFrameContext) or
part of a parent context.

This change introduces an uglification of the use of getSVal(), and thus takes
two steps forward and one step back.  There are also potential performance implications
of enlarging the Environment.  Both can be addressed going forward by refactoring the
APIs and optimizing the internal representation of Environment.  This patch
mainly introduces the functionality upon when we want to build upon (and clean up).

We are getting name of the called function or it's declaration in a few checkers. Refactor them to use the helper function in the CheckerContext.

Also document addTransition methods.

llvm-svn: 143059

Remove dead members/parameters: ProgramState, respondsToCallback, autoTransition.
Remove addTransition method since it's the same as generateNode. Maybe we should
rename generateNode to genTransition (since a transition is always automatically
generated)?

Cleanup various declarations of 'Stmt*' to be 'Stmt *', etc. in libAnalyzer and libStaticAnalyzer[*].  It was highly inconsistent, and very ugly to look at.

   CStringChecker
   ChrootChecker
   MallocChecker
   PthreadLockChecker
   StreamChecker
   UnreachableCodeChecker

MallocChecker creates implicit dependencies between checkers and needs to be handled differently.

Split 'include/clang/StaticAnalyzer' into 'include/clang/StaticAnalyzer/Core' and 'include/clang/StaticAnalyzer/Checkers'.

This layout matches lib/StaticAnalyzer, which corresponds to two StaticAnalyzer libraries.

layout.  :)

Rename the 'EntoSA' directories to 'StaticAnalyzer'.

Internally we will still use the 'ento' namespace
for the analyzer engine (unless there are further
sabre rattlings...).
