We are talking about Thumb2 here right? Any reason we cannot just enable that
too? Does it have to do with the encoding of the EOR instructions? Because in
that case, I will reiterate the point I made previously, i.e., that we should
be able to decode the expected signature in the exception handler by XOR'ing
with the observed signature, and not look at the opcodes at all.
