Refine the error message of unused ivars.
Added test case.

When constructing an ObjCIvarDecl object in Sema, provide its visibility up front instead of setting it afterwards.
This change also fixes a subtle bug where the access control of an ivar would be initialized to garbage if we didn't have an explicit visibility specifier (e.g., @private).

is protected, not private.

Added ObjCIvarDecl::getCanonicalAccessControl() to report the visible access
control of an ivar, whereas getAccessControl() returns the access control
relating to how the ivar was actually declared.

Fix protocol lists to pass down proper location info, so we get diagnostics
like this:

t.m:3:35: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
                                  ^

instead of this:

t.m:3:44: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
                                           ^
