-Subject: ia64: Fix crash in thread context switch.

-The problem here is the value of 't->pending_rbs_continuation' pointer.
-It's supposed to poin to a register stack pointer or be NULL if not yet
-backed up.
-
-The problem is it is never initialized to NULL at creation time and
-contained garbage on stack. Sometimes people are lucky and have zeros
-on stack and guile works. But sometimes there is something and guile
-crashes.
-
-The fix is trivial: initialize 'pending_rbs_continuation = NULL'
-at thread registration time (the same way other threads are registered).

-* libguile/threads.c (guilify_self_1): Initialize pending_rbs_continuation
-to avoid crash on ia64.
