Tweak API of new function clause_is_computable_at().

Browse Source 
Pass it the RestrictInfo under consideration, not just the
clause_relids.  This should save some trivial amount of
code at the call sites, and it gives us more flexibility
about what clause_is_computable_at() does.  There's no
actual functional change here, though.
