[spacer] implement spacer::is_clause() (#4170) 
Spacer has a different defintion of is_clause() than ast_util.
It is currently only used in assertions.

Main difference:
  x=y
where x and y are Bool atoms is considered to be an atom, so that
(or (= x y) (not (= z y)))
is a literal

Improve UX for unreachable/unimplemented errors (#4094) 
This should replace several "segfaults" and "illegal instruction" errors
with messages that contain a bit more context. I also put in a link to
the bug tracker to make users' lives a bit easier.

For context, `__builtin_unreachable`'s behavior is undefined and is
intended only as a mechanism to help the compiler see that code will not
return. I do still include it in the new code because if I don't,
compilation produces a lot more warnings as it can't see that
`NOT_IMPLEMENTED_YET` and `UNREACHABLE` cannot return.
