Richard,

Will it be a good idea to have a twos-complement architecture hook? In case of
x86 we can reassociate since the architecture itself always behave as
twos-complement. So introducing such a flag can help with this particular
reassociation and another one that Ilya Enkovich implemented recently.

What's your opinion?
