Message:

In egc_svset, don't use %temp0 to access refbits. (pc_luser_xp() assumes
that if the pc is within egc_svset, %temp0 contains the vector and tries
to emulate the store.) It should be safe to use %temp1 instead, since
the refbits address should be fixnum-tagged and outside the lisp heap
(so it doesn't matter whether the caller things %temp1 is a node or not.)

This machine needs more registers ...
