Remove bogus assertion in getCallMethod
With my as-yet-uncommitted changes to the demand analyzer, code got
generated for some programs that caused this assertion to fail. The

Make the LiberateCase transformation understand associated types
Consider this FC program:
data family AT a :: *
data instance AT Int = T1 Int Int
f :: AT Int -> Int
f t = case t of DEFAULT -> <body>
We'd like to replace the DEFAULT by a use of T1, so that if
we scrutinise t inside <body> we share the evaluation:
f t = case (t `cast` co) of T1 x y -> <body>
I decided to do this as part of the liberate-case transformation,
which is already trying to avoid redundant evals.
The new transformation requires knowledge of the family instance
environment, so I had to extend ModGuts to carry the fam_inst_env,
and put that envt into the liberate-case environment.
Otherwise it's all pretty straightforward.

Log message for: Fix a nasty recursive loop in typechecking interface files
(Alas, Darcs failed to record my log-message for the above patch,
so this patch is an attempt to add the log message retrospectively.)
Roman found a case where the type-checker for interface files
would go into a loop. Here it is:
module BarAT where
class Foo a where
data FooT a :: *
int :: FooT a -> Int
module Baz where
import BarAT
foo :: FooT Int -> Int
foo = foo
The trouble turned out to be that Foo gives rise to a *newtype*,
and using a newtpe caused a little bit too much strictness in
BuildTyCl.mkNewTyConRhs. Specifically, mkNewTypeCoercion did pattern
matching, which forced the call to eta_reduce in mkNewTyConRhs.
This is all too delicate really. But for now I've fixed the bug,
and added an explanatory comment. I'll add a test for it, in

While I was at it, I changed the syntax for standalone deriving, so that
it goes
derive instance Show (T a)
(instead of "derive Show for T"). However, there's still an implicit
context, generated by the deriving code, and I wonder if it shouldn't really
be
derive instance (..) => Show (T a)
