I don't think I introduced it (was it Devang?).  However, I agree with  
duncan: the right fix is to make the StructTypeInfoMap be indexed by a  
GCC type, not an llvm type.  I am not fully familiar with how  
StructTypeInfoMap works, but I wouldn't be surprised if this caused  
other subtle miscompilations.
