Chris Lattner c77d24b792 make instcombine only rewrite a chain of computation 
(eliminating some extends) if the new type of the
computation is legal or if both the source and dest
are illegal.  This prevents instcombine from changing big
chains of computation into i64 on 32-bit targets for 
example.
