This patch bootstrapped with no new regressions last night on x86 linux.
This is what it looks like. I have no special attachment to the namings,
I considered DEREF_DEF and DEREF_USE instead of DEF_FROM_PTR and
USE_FROM_PTR, maybe they would be better names...  I described the
interface at the beginning of this thread on gcc-mailing-list yesterday.

I'll send the LNO version in a different note.
