99c91e021a 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.

031a112747 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
to int.
