Change syntax for newtypes in External Core
The way that newtype declarations were printed in External Core files was
incomplete, since there was no declaration for the coercion introduced by a
newtype.
For example, the Haskell source:
newtype T a = MkT (a -> a)
foo (MkT x) = x
got printed out in External Core as (roughly):
%newtype T a = a -> a;
foo :: %forall t . T t -> t -> t =
%cast (\ @ t -> a1 @ t)
(%forall t . T t -> ZCCoT t);
There is no declaration anywhere in the External Core program for :CoT, so
that's bad.
I changed the newtype decl syntax so as to include the declaration for the
coercion axiom introduced by the newtype. Now, it looks like:
%newtype T a ^ (ZCCoT :: ((T a) :=: (a -> a))) = a -> a;
And an external typechecker could conceivably typecheck code that uses this.
The major changes are to MkExternalCore and PprExternalCore (as well as
ExternalCore, to change the External Core AST.) I also corrected some typos in
comments in other files.

Beware kludgy use of z-encoding and gratutious copy-pasta from GHC.
You can now use the stand-alone Core parser to parse a very simple
GHC-generated .hcr file (progress!) but not to typecheck or interpret it
(the typechecker/interpreter don't snarf in the right libraries yet, among
other things.) And, the parser is still incomplete in that it doesn't handle

* Be less keen to specialise on variables that are simply in scope.
