Brian Gaeke 7610971759 It seems likely that floats would need a cast too, because they are 
ordinarily promoted to doubles.

Chris Lattner 834105502d Do not mark ALL terminators live if any instruciton in the block is live. We only 
want to mark it live if it is an unconditional branch.  This fixes bug:
ADCE/2002-05-28-Crash.ll and makes this pass _much_ more useful.

Brian Gaeke 04bdfe624c Fix 2003-06-23-PromotedExprs.llx -- if we are adding two bytes we better 
explicitly cast the result to be a byte, or C will gleefully promote it
