Got it.  The real difference is:

        alloc r34 = ar.pfs, 1, 3, 1, 0
+.LCFI0:
        addl r14 = @ltoffx(_xexit_cleanup#), r1

i.e. the dwarf2 cfi stuff isn't creating debug labels,
which means we break the bundle and add nops where we
didn't want em.

Hopefully I'll have a new patch this afternoon so you
can do overnight tests.
