[PATCH 0/3] Support for x86 segments as address classes

The following gets 90% of the way there, but I'm stuck --
address_to_pointer and pointer_to_address do not appear to
have access to a regcache. And not just in the one level
of the caller, but significantly farther back in the call
stack too.
Which begs the question of whether I've simply missed
something in how to get hold of the current regcache?
