4d5b50dee9 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.

654b7df1de 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.

c01b239779 Refactor struct type representation. 
- fields now represented by fld struct.
 - mutability on per-field basis
 - accessors are per field

This fixes lots of existing bugs, allows future #:mutable on fields.
