Updated comment for class ObjCIvarDecl: it turns out the default access control

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.
