b19cac5fab Add simplification rule: t1 == min (K + t1) t2 ~> t1 == t2, if K >= 1. 
Fixes #494.

d58aebcee8 Fix shadowing warnings in example cryptol code. 
Shadowing a name from the Cryptol prelude produces an unpredictable
warning message with a temporary file name, which is not good for our
regression test suite.

d803192b2b Add regression test that loads all modules from examples directory. 
This file should be updated every time a new module is added to
`examples`.

Fixes #529.

b812241481 Fix type error in examples/Karatsuba.cry. 
The error was caused by the recent change of the type of `demote`
when class `Literal` was introduced.

a66338293a Memoize result of binary logic operators on LargeBitsVal arguments. 
Fixes #446.

This fix is very similar to the one for #514, which added memoization
for symbolic if-then-else on sequences. This is another instance where
a SeqMap is created where each lookup triggers two further lookups,
causing exponential runtime behavior in the worst case.

This seems to have been broken when the desugaring of [_ ..] was
changed.

7259507d04 Unifier now returns a substitution even on unification failure. 
For example, when type checking `[1..10]:[6][8]`, `mgu` would be called
on [10]?a and [6][8], and `mgu` would return the substitution `?a = [8]`
and the mismatch error `10 != 6`.

Fixes #525.

c925a82dce Update function toExpr for new type of demote primitive. 
Also avoid using removed primitive `integer`.

Previously this caused a panic when printing counterexamples
of type Integer.

6f67924894 Add some more simplification on user defined signatures. 
This is not great, but since we do it, we should do it more consistently.
Avoids a panic in the bench mark suite (more generally, when users write
trivial things in their type signatures, eg. see `pad` in SHA512)

This mostly takes care of #154, but we still need tab-completion.

844e80085d Print ambiguous command warning for :help with ambiguous command name. 
For example:

Cryptol> :help :c
:c is ambiguous, it could mean one of:
	:cd, :check

Previously we would print the help text for all matching commands,
which was a bit much.

99773d71b7 Memoize result of symbolic if-then-else on sequence types. 
It is important that we memoize `mergeSeqMap`: Because one
lookup into the merged sequence leads to two other sequence
lookups, the lack of memoization could led to exponential runtime
behavior in the worst case.

Fixes #514.
