[LLVMdev] LLVM build fails using gcc-4.7.0 and -std=c++11 flags

I just updated my llvm sources (revision 164794.) and I see the error, 
"overriding non-deleted function" when building with gcc 4.7.0 and 
passing -std=c++11.

[LLVMdev] LLVM build fails using gcc-4.7.0 and -std=c++11 flags

I've fixed this specific error in r164813. Please let me know if there are
more behind it.

I pulled this version, 164813 and the latest which is 164821 and I see 
essentially same error, the line number changed from 38 to 40.

The problem seems to stem from the addition of LLVM_DELETED_FUNCTION.  I 
reverted back to a version that doesn't have this the build proceeds 
without issue.

While this probably isn't the correct fix, I removed all instances of 
LLVM_DELETED_FUNCTION from Operator.h and this allowed the build to 
complete.  I don't know if it is the redundant use of delete or a 
problem with gcc-4.7.0

Here are the specifics from a build using the unmodified revision, r164813:
