This class will represent types that can be meaningfully compared for
signed bitvector equality. It lifts the comparison operations on
nonempty bitvectors through tuples, records and finite sequences via
lexicographic order.

Removed definition of binary infix (~) from Cryptol prelude. Fixes #423 .

This change partially reverts changeset c620cbf2

As of this change, `:t (~)` will no longer work in the REPL.
The regression test for issue #296 is removed.

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.

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.

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.
