    ghc/compiler/simplCore Simplify.lhs 
  Log:
  1. Remove redundant coerces.  Something that started life as
  	coerce a b <expr>
     might change to
  	coerct Int Int <expr>
     after the types a,b are instantiated.
  
  2. Get rid of the "bad eta expand" message. It can happen entirely legitimately.
     See comments in CoreUtils with eta_expand.
  
  	MERGE TO STABLE
