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.

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.

Avoid boxing intermediate results when doing multiple complex
...
operations in a row.
However, because of values and let-values, we lose float unboxing.
If we have a single complex operation, this is much slower than my
previous implementation (though still faster than generic
operations). With 2 complex operations, the new implementation becomes
faster.
