bjh21 8805bd8b56 Unify arm26 and arm32 trapframe structures. The unified trapframe is the same
shape as the old arm32 one, but there are a few #defines to keep arm26 code
happy.  Anything that depends on the precise shape of the trapframe,
and especially on being able to treat it as an array of registers, has been
updated.
