Dan Scales 7e9f911ec4 [dev.typeparams] cmd/compile: remove some shape checks in type substituter, other cleanups
The type substituter (typecheck.Typ()) was temporarily substituting from
shapes back to concrete types, but doesn't need to anymore. So, remove
two shape checks, so the type substituter is now only for substituting
type params again.

Several other cleanups:

 - renamed makeGenericName() to makeInstName1(), since that function is
   a helper to MakeInstName() and MakeDictName() that definitely makes
   instantiated names, not generic names.

 - removed the logic in makeInstName1() that adds the ".inst." prefix
   for concrete type args. We are only specifying concrete type args (as
   opposed to shape args) when we are calling from MakeDictName, and
   then we immediately strip of the .inst prefix anyway.

 - Added a comment on types.Identical that a shape type is considered
   identicall to another type if their underlying types are the same, or
   they are both pointers.
