Ariel Ben-Yehuda 37c569627c refactor constant evaluation error reporting
Refactor constant evaluation to use a single error reporting function
that reports a type-error-like message.

Also, unify all error codes with the "constant evaluation error" message
to just E0080, and similarly for a few other duplicate codes. The old
situation was a total mess, and now that we have *something* we can
further iterate on the UX.
