Created an attachment (id=7537)
 --> (http://llvm.org/bugs/attachment.cgi?id=7537)
sample objective-c program to explain the bug

As per Objective-C documentation, readonly attribute can't be used in a
property declaration along with the setter attribute.

Documentation 
==========
Quoted from the document The Objective‐C Programming Language (page 71)

"If you specify that a property is readonly and also specify a setter with
setter=, you get a compiler warning."

Sample Program
==========
see attachment for small program in objective-c explaining the problem

Actual behavior:
==========
Clang doesn't throw an error in line 20 in the attached program

Expected Behavior
===========
Clang should throw an error stating that "setter cannot be specified for a
'readonly' property ‘n1’"

Pls can you pls fix this, let me know if you need more information.
