Partition out declarations that should be monomorphic, based on what they
reference in the environment; declarations that lack signatures but don't
reference anything in the local environment can still be generalized.
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.
This tries to address #125 by making the errors from the renamer a little bit
more clear.

Remove a shadowing warning
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.
