80343e7256 Don't generalize bindings in where clauses
A first pass on skipping generalization for bindings in a where clause that
lack type signatures.  The tests that fail as a result of this change are either
because of error locations changing, or a changing number of defaulting
warnings.

ccfbd1f2de Fix symbolic simulator implementations of (!!) and (@@)
Now these operations correctly set the is-bit flag on
the VSeq constructor when the result type is a list of bits.

Fixes #148.

6368bcbe38 Make evaluation of lists of bits non-strict in the elements.
This means that e.g. [True, error "foo"]@0 evaluates to True,
similar to how [0x1, error "foo"]@0 evaluates to 0x1.

b05ddd5e54 Partially fixes #73
Due to the limitations of the GHC runtime, we can't get around the
possibility of out-of-memory errors, but we can prevent individual
bitvectors from being too large for the libgmp-backed bignums.

There is now an architecture-dependent check whenever creating a new
`BV` value in the concrete evaluator to ensure the width does not
exceed the GMP limits. If a width is too large, the evaluation returns
to the REPL much like diving by zero.
