Thumb2ITBlockPass: Fix a possible dereference of an invalid iterator. This was
introduced in r106343, but only showed up recently (with a particular compiler &
linker combination) because of the particular check, and because we have no
builtin checking for dereferencing the end of an array, which is truly
unfortunate.
