785687a67f Add new vector update primitives 'update' and 'updateEnd' which update
vectors at indices starting from the beginning/end of the vector,
respectively.

Included in this patch are implementations of these primitives
for the concrete evaluator.  Symbolic primitives are TODO.

e31b4ba57d WIP. Improve performance of the new evaluator.
To get acceptable performance, we need to be pretty aggressive about
using word representations instead of list-of-bits.  Unfortunately,
with the new evaluator, this means we force things to be more strict
than is correct.

We are also still slower than the current evaluator.  It is not
clear where the problems are.

7e968d2d18 WIP. New monadic Cryptol interpreter.
The concrete evaluator now seems to be working correctly,
but seems to suffer from major performace problems.

c620cbf237 Update the parser to allow prefix operators in more places.
This allows us to define (~) as a prefix operator symbol synonym
for `complement`.

Fixes #296.

da6916702b split new Prelude definitions into Extras module
The definitions added in #299 cause a regression in Prelude typechecking
performance. Until we sort out the performance, we'll keep these
definitions in the module `Cryptol::Extras`.

07da2018b7 switch to more portable seeding for random
The `random` primitive previously took a `[32]` seed, but this causes
inconsistency between 32-bit and 64-bit platforms when the seed is large
enough to wrap around in GHC's representation of an `Int`. This patch
switches to an API that seeds directly with four 64-bit words, and so
should behave the same way on our supported platforms.

68f71ed3b3 Add some Haskell-like prelude functions.
Implication  (==>), not, and, or, all, any, map, foldl, sum, scanl, extend,
extendSigned, foldr, scanr, zip, zipWith, repeat, curry, uncurry, and elem.

Rationale:

I've had to implement these functions several times for different problems.
While my problems were admittedly toy, not cryptographic, the functions are
generally applicable and unlikely to clash with many, if any, preexisting
operations of different semantic meaning.

e87d0469ab Fix incorrect docstrings for polynomial operations
pmult, pdiv, and pmod are not specific to GF(2^^8);
they work on polynomials of arbitrary size with
elements drawn from GF(2).

6a7477ba6c Half-fix but not quite issue #256 (Bool ~> Bit).
We should probably discuss why we want to call things "Bool" if this was
more concious than incidental.  That and change the documentation to
match.
