Refine ObjCPropertyImplDecl:

interface, and makes the object immutable until we have a reason to be mutable.

- Remove instance variable 'PropertyImplKind PropertyImplementation;'. This is
not needed because we can tell if ObjCPropertyImplDecl represents @synthesize
if 'ObjCPropertyDecl *PropertyDecl' is not null.

Switch initialization of the protocol list for an interface decl to use
...
the standard "set these as the list of protocols" interface instead of a
strange "set this as the size and then set each one to the value" interface.
The problem with the later is that it a) is completely different from
everything else, b) is awkward, and c) doesn't handle the case when a
referenced protocol is invalid: it set it to null.
This meant that all clients downstream would have to handle null protocols
in the protocol list, and empirically they didn't. Fix this by not setting
invalid protocols in the referenced protocol list, fixing the crash on
test/Sema/objc-interface-1.m
While I'm at it, clean up some locations so that we produce:
t.m:1:25: error: cannot find interface declaration for 'NSObject', superclass of 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>

AnalysisConsumer #includes this file to generate the switch statement to create
actions.
Renamed -check-objc-methodsigs to -warn-objc-methodsigs.

Add some code to handle vector comparisons, which is the language side
of the llvm vicmp/vfcmp instructions. Also make the vector-vector and
vector-scalar asign checks a bit more sane under the presence of lax vector

Initial work on splitting the ValueState into an Environment, Store, and
...
Constraints. These concepts are already present in the current ValueState, but
the implementation is monolothic. Making ValueState more modular opens up new
design choices for customizing the analysis engine.
In the context of the analysis engine, the "Environment" is the binding between
Expr* (expressions) and intermediate symbolic values (RValues).
