e903b419dd Avoid resolving types when checking subtyping on structs. 
This fixes problems with caching, because sometimes we were giving the wrong answer for nested calls to `subtype'.

f0bdca6383 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.

3d6b5893ba 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.

d5941cb2d6 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.

134fb72de1 Further fixes in overlap checking. 
Rhss of code dispatching on overlapping structs are no longer
considered dead, and as such, are now typechecked.

Had to fix a test that passed only because some not-really-dead code
was not being typechecked.

f3a78d1e10 Two fixes in overlap checking. 
- Names were not being resolved, so a superstruct name and substruct name
   could be seen as non-overlapping.
 - Struct parents were not checked in the overlapping algorithm.
