[objc-arc] Add the predicate CanDecrementRefCount. This is different from CanAlterRefCount since CanDecrementRefCount is attempting to prove specifically whether or not an instruction can decrement instead of the more general question of whether it can decrement or increment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229936 91177308-0d34-0410-b5e6-96231b3b80d8
