dda5d34131 Fix constraints on type of primitive intmod. 
The old type did not forbid literals of the invalid type `Z inf`.

59104829a0 Rename Cryptol.Utils.PP.<> to avoid clash with Semigroup operator. 
The pretty-printing operator `<>` is now called `<.>`.

Cryptol now compiles without warnings on both ghc 8.2 and 8.4.

4f1a743585 Remove special cases in evaluator for types Z 0 and Z inf. 
These types are now forbidden by the type checker.

7da2219caf Initial implementation of type Z n (integers mod n). 
This covers most of #510, including the type itself and the
class instances, but not any of the new primitive functions.

083d42ad30 Remove integer-based arguments to logicUnary and logicBinary. 
Type `Integer` is not an instance of class `Logic`, so we don't need
to implement logic operations for this type.

6b3dc6d9d4 For quick-checking integer properties, use a randomized bit width. 
The distribution is unbounded, but is biased to smaller bit widths,
and is designed to have an average bit-width of 64.

ab000984d2 Remove redundant prelude functions not, extend, and extendSigned. 
These were recently moved here from Cryptol::Extras. They are duplicates
of existing functions `complement`, `zext`, and `sext`.

See #427.

13363c4c9b fastTypeOf doesn't perform any simplification when substituting types. 
This makes it more useful for the saw-core translation, because we
can notice when type coercions need to be applied.

ec5e84dd37 Add a fin constraint on following matches in a comprehension. 
Fixes #505.   It doesn't really make sense to have infinite things
following a finite thing in a comprehension, as there would be a whole
lot of unreachable elements.  Since this is likely an error, we try
to catch it with the types.

126c384ff6 Avoid most recent version of base-compat 
The latest version causes build failures. Ultimately, we should be able
to fix the code to work with newer base-compat versions on various GHC
verions, but this gets builds to work for now.
