-------------------
	Fix a subtle GC bug
	-------------------

In GHC 6.0, the top-level definition

	f = g

gets compiled as a *non-updatable* THUNK_STATIC closure.  Being non-updatable,
it gets only 1 payload field.  Alas, the static-link field for a THUNK_STATIC
goes in the 3rd payload field.  Disaster.

Solution: make such things updatable. This is probably good because it turns
f into an IND_STATIC, which gets shorted out.  (Even better would be to allocate
an IND_STATIC in the first place.)
