re PR libobjc/11433 (Crash due to dereferencing null pointer when querying protocol)
PR 11433
gcc/testsuite:
* objc.dg/proto-lossage-3.m: New test.
libobjc:
* Protocol.m (descriptionForInstanceMethod): Don't dereference
instance_methods if it's NULL.
(descriptionForClassMethod): Likewise for class_methods.
