What steps will reproduce the bug?

• Start node repl with experimental top level await
  node --experimental-repl-await
• Run the following code in the REPL
  foo(); const x = await Promise.resolve(1); function foo() { console.log('Do Something');}
  The following error is displayed

Uncaught TypeError: foo is not a function
    at REPL1:1:32

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior?

Function foo should be hoisted and available.

Repl errors out.

I believe I have a solution (see PR, currently WIP here #39745).
