Updated TR's base type environment to use the new numeric types.

This ended up being an almost complete rewrite of the base environment.
Note: While the commit is dated Jan 27, the work was finished on Mar 2.

Add a predicate field to base types, which makes checking for
...
subtyping of value types easier.
However, this means that base types can't be marshaled as before,
since these predicates can't be marshaled. Instead, we now marshal
base types as identifiers that refer to their base type object.

TR's numeric tower is now built from unions of non-overlapping base types.
...
A lot of the work that was done by special-casing number types can now be
done by TR's handling of unions. This makes it easier to add more numeric
types to the tower and should make writing down types for numeric
primitives much less error-prone.
In addition, this commit adds several numeric types that will help get
tighter bounds on integer arithmetic, such as Index types. They will have
to be integrated to the base environment before they can be useful.

Create a mzlib/contract compatible version of the old box/c and use that

Fix the typed-scheme implementation to only force flat box (or hash)
contracts when it already is required to be flat. Otherwise, allow
non-flat contracts for the element contract (or domain/range contracts).
