As part of the work to make Objective-C type information
from symbols more accessible, I have added a second
map to the ClangASTImporter: the ObjCInterfaceMetaMap.
This map keeps track of all type definitions found for
a particular Objective-C interface, allowing the
ClangASTSource to refer to all possible sources when
looking for method definitions.
There is a bug in lookup that I still need to figure out,
but after that we should be able to report full method
information for Objective-C classes shown in symbols.
Also fixed some errors I ran into when enabling the maps
for the persistent type store. The persistent type store
previously did not use the ClangASTImporter to import
types, instead using ASTImporters that got allocated each
time a type needed copying. To support the requirements
of the persistent type store -- namely, that types must be
copied, completed, and then completely severed from their
origin in the parser's AST context (which will go away) --
I added a new function called DeportType which severs all
these connections.

[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.

ExprEngine.
Teach SimpleConstraintManager::assumeSymRel() to propagate constraints
to symbolic expressions.

[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.
