<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fall back to types when looking up data constructors (#18740)

Before this patch, referring to a data constructor in a term-level
context led to a scoping error:

    ghci> id Int
    <interactive>:1:4: error: Data constructor not in scope: Int

After this patch, the renamer falls back to the type namespace
and successfully finds the Int. It is then rejected in the type
checker with a more useful error message:

    <interactive>:1:4: error:
    Type constructor 'Int' used where a value identifier was expected

We also do this for type variables.
