Quick adaption of JIT tuple deforming to the fast default patch.

Browse Source 
Instead using memset to set tts_isnull, call the new
slot_getmissingattrs().

Also fix a bug (= instead of >=) in the code generation. Normally = is
correct, but when repeatedly deforming fields not in a
tuple (e.g. deform up to natts + 1 and then natts + 2) >= is needed.
