6e19896999 Objective-C was generating EH frame info like this:
"_-[NSString(local) isNullOrNil]".eh = 0
        .no_dead_strip  "_-[NSString(local) isNullOrNil]".eh

The ".eh" should be inside the quotes.

8c33da5dc4 Fix for PR1633: Verifier doesn't fully verify GC intrinsics
LLVM now enforces the following prototypes for the write barriers:

<ty>* @llvm.gcread(<ty2>*, <ty>**)
void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**)

And for @llvm.gcroot, the first stack slot is verified to be an alloca or a 
bitcast of an alloca.

Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these.
