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].

There were two bugs here:
1. Treating type-level constructors as PromotedDataCon doesn't always
work, in particular because constructors promoted via DataKinds are
called both T and 'T. (Tests T22332a, T22332b, T22315a, T22315b)
Fix: guard these cases with isDataKindsPromotedDataCon.
2. Type-level constructors were sent to the code generator, producing
things like constructor wrappers. (Tests T22332a, T22332b)
Fix: test for them in isDataTyCon.
Other changes:
* changed the marking of "type data" DataCon's as suggested by SPJ.
* added a test TDGADT for a type-level GADT.
* comment tweaks
* change tcIfaceTyCon to ignore IfaceTyConInfo, so that IfaceTyConInfo
is used only for pretty printing, not for typechecking. (SPJ)
