Change references to 'const ProgramState *' to typedef 'ProgramStateRef'.
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.

[analyzer] Refactor: Move symbol_iterator from SVal to SymExpr, use it
for finding dependent symbols for taint.

[analyzer] Propagate taint through NonLoc to NonLoc casts.
- Created a new SymExpr type - SymbolCast.
- SymbolCast is created when we don't know how to simplify a NonLoc to
NonLoc casts.
- A bit of code refactoring: introduced dispatchCast to have better
code reuse, remove a goto.
- Updated the test case to showcase the new taint flow.

[analyzer] Unify SymbolVal and SymExprVal under a single SymbolVal
class.
We are going into the direction of handling SymbolData and other SymExpr
uniformly, so it makes less sense to keep two different SVal classes.
For example, the checkers would have to take an extra step to reason
about each type separately.
The classes have the same members, we were just using the SVal kind
field for easy differentiation in 3 switch statements. The switch
statements look more ugly now, but we can make the code more readable in
other ways, for example, moving some code into separate functions.

[analyzer] Remove all uses of ConstraintManager::canResonAbout() from
ExprEngine.
Teach SimpleConstraintManager::assumeSymRel() to propagate constraints
to symbolic expressions.
+ One extra warning (real bug) is now generated due to enhanced
assumeSymRel().

[analyzer] First step toward removing
ConstraintManager::canReasonAbout() from the ExprEngine.
ExprEngine should not care if the constraint solver can reason about
something or not. The solver should be able to handle all the SymExprs.
To do this, the solver should be able to keep track of not only the
SymbolData but of all SymExprs. This is why we change SymbolRef to be an
alias of SymExpr*. When encountering an expression it cannot simplify,
the solver should just add the constraints to it.

now that we have a centralized place to do so, add some using declarations for

quite a bit.

Step #1/N of implementing support for __label__: split labels into
LabelDecl and LabelStmt. There is a 1-1 correspondence between the
two, but this simplifies a bunch of code by itself. This is because
labels are the only place where we previously had references to random
other statements, causing grief for AST serialization and other stuff.
This does cause one regression (attr(unused) doesn't silence unused
label warnings) which I'll address next.
This does fix some minor bugs:
1. "The only valid attribute " diagnostic was capitalized.
2. Various diagnostics printed as ''labelname'' instead of 'labelname'
3. This reduces duplication of label checking between functions and blocks.
Review appreciated, particularly for the cindex and template bits.

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.
