244848326c Special case for svFromInteger at bit width 0. Fixes #563. 
This change ensures that `fromInteger x : [0]` is concrete,
even if `x` is symbolic.

b1edb9e36e No more rebindable syntax. Fixes #568. 
When syntactic sugar for constants "negate", "complement" or "splitAt"
is used, the names of those primitives are now resolved during the
type checking phase. This makes them consistent with the handling of
other desugared primitives like "fromThen", etc.

8d09c79198 Make Cryptol compile with SBV 8.0 
SBV 8.0 is now on hackage, with several backwards compatibility breaking changes. You'll need this patch to compile cryptol against it.

b801e6677e Fix satNum 
Since SBV 7.0; allSat is no longer lazy. So, Cryptol's current
implementation is buggy:

   Cryptol> :set satNum=2
   Cryptol> :sat \x -> x >(3:Integer)
   .. Runs forever ..

This pull request fixes the issue:

   Cryptol> :set satNum=2
   Cryptol> :sat \x -> x>(3:Integer)
   (\x -> x > (3 : Integer)) 4 = True
   (\x -> x > (3 : Integer)) 5 = True
   (Total Elapsed Time: 0.000s, using Z3)

Note that if you set `satNum` to be `all` and if there are indeed an
infinite number of satisfying models, SBV (and thus Cryptol) will still
loop forever. There's really no good way to solve that problem,
unfortunately.

a8eab11b31 Changes to avoid irrefutable patterns. 
This is to make things build with GHC 8.6, which requires a MonadFail
instance.

Pretty much all of these should end up being `panic`, so perhaps we should
rewrite more of them to call `panic` (instead of using lazy patterns)

ad766b3aa7 Reformulate the property, so that Z3 can still find models. 
With the other formulation, Z3  became really bad at finding any kind
of model.  Basically, it would always answer `unsat` or `unknown`.

This is undesirable, because we use models when instantiating things
at the command line.  In those cases, however, we probably don't
need the rule at all...  Perhaps, we should provide a way to disable
the axioms when we are looking for models?

3caa3a8e82 Use 32-bit GMP size limit on unknown architectures 
There doesn't seem to be a general-purpose way to determine architecture
word sizes from CPP as invoked by GHC, so we now fall back on the 32-bit
GMP size limit for unknown architectures. This is always safe, and can
be amended to allow larger words on other architectures as needed.

Closes #542.
