This subsumes Nico Weber's patch and implements bzero in terms
of llvm.memset to match llvm-gcc.

This closes <rdar://problem/6080720>, support for __builtin_constant_p
has been filed separately.

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>
~~~~~~~~~~~~~~~~~~~~~   ^

instead of:

t.m:1:1: error: cannot find interface declaration for 'NSObject', superclass of 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
^

void test2(NSNumber x) {

}

which doesn't make sense and GCC rejects.

When in C++, make EnumConstant names hide tag names in the same scope, instead of colliding with them.

This fixes <rdar://problem/5987211> clang ObjC rewriter: @try / @finally block produces unbalanced output.

When checking for name collision between a tag and a previously defined namespace, the collision occured even when the tag was in a different nested scope.
Fix it by taking into account the scope when checking for namespace-tag name collisions.

Provide an "Analysis Scope" for Analyses so checks can either be run on code declarations (bodies) or Objective-C @implementation blocks.

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
conversions.

ObjCImplementationDecls and sees if a ancestor class defines a method with the
same selector but with a different type signature. Right now it just compares
return types, and mainly looks at differences in primitive values. The checking
will be expanded in the future.

Essentially the observer mechanism in LiveVariables was observing block-level
expressions multiple times, leading to a case where the dead store checker could
see a value as dead when it was really live.

Added static analysis check to see if a subclass of NSObject implements -dealloc, and whether or not that implementation calls [super dealloc].

Update test case:  simply running "clang -checker-simple" doesn't invoke the dead store checker anymore.  We need "-warn-dead-stores" as well.
