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>
^

Replace CurFunctionDecl and CurMethodDecl with methods getCurFunctionDecl() and getCurMethodDecl() that return the appropriate Decl through CurContext.

llvm-svn: 52852

The assert at Sema::ObjCActOnStartOfMethodDef should check CurMethodDecl instead of CurFunctionDecl.

Second half of "fix" for <rdar://problem/5986085> clang on xcode: error: redefinition of 'XCElementToggler' as different kind of symbol

- Changed Sema::ObjCActOnStartOfMethodDef() to more accurately type "self" in factory methods.
- Changed Sema::ActOnInstanceMessage() to use the new type to restrict the lookup.

Mostly semantic checking in this patch. This is on going
