New Revision: 109742

URL: http://llvm.org/viewvc/llvm-project?rev=109742&view=rev
Log:
When unifying instructions during a block diff, actually complain about
any differences we see.  This should only happen if there are "non-structural"
differences between the instructions, i.e. differences which wouldn't cause
diff to return true.
