unify the code that determines whether it is a good idea to change the type
...
of a computation. This fixes some infinite loops when dealing with TD that

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.
