[cfe-dev] default instance variable visibility

[Emerson Murphy-Hill]

I noticed when clang parses objective-c interfaces, the default  
visibility for instance variables is private.  For example, in this code

@interface Bloo {
     int somevar;
}

somevar is reportedly private visibility, by getAccessControl on  
ObjCIvarDecl.  I believe that default visibility is supposed to be  
protected:

Here's a patch:

variables.
    while (Tok.isNot(tok::r_brace) && Tok.isNot(tok::eof)) {
