Matthew Flatt 3c382284a4 cs: better equal-secondary-hash-code 
Since CS doesn't use secondary hash code internally, the
`equal-secondary-hash-code` function wasn't really implemented.
Implement it reasonably for applications that might use it to
implement other data structures.

Testing exposed other problems related to error reporting for a broken
hash-function result and for using values within immutable hash
tables.

Closes #3536
