d4c93cc12e 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.

e011ea00bd Further improvements for TR's error messages. 
Only the most permissive domains whose associated return type is
consistent with the expected type are shown in error messages.

For example, for a function with the following type:
Fixnum -> Fixnum
Integer -> Integer
and an expected type of Integer, only the latter domain is shown in
the error message.

206fe52047 Improved TR's error messages in presence of case-lambda types. 
- When displaying errors involving functions that have case-lambda
  types with branches that are redundant modulo filters (such as <, >
  and others), only the general branches appear in the error message.
  (Real Real Real * -> Boolean, in the case of < and co.).
- For all errors involving case-lambda types, only domains for which
  the return type is consistent with the expected type are displayed
  in the error message. Further simplification is planned.
