The SelectionDAGBuilder's handling of debug info, on rare

occasions, caused code to be generated in a different order.
All cases I've seen involved float softening in the type
legalizer, and this could be perhaps be fixed there, but
it's better not to generate things differently in the first
place.  7797940 (6/29/2010..7/15/2010).
