Define `Infinite` list and use where appropriate.
Also add perf test for infinite list fusion.
In particular, in `GHC.Core`, often we deal with infinite lists of roles. Also in a few locations we deal with infinite lists of names.
Thanks to simonpj for helping to write the Note [Fusion for `Infinite` lists].
